+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.

+# Contributing to semantic-release
+
+✨ Thanks for contributing to **semantic-release**! ✨
+
+As a contributor, here are the guidelines we would like you to follow:
+- [Code of conduct](#code-of-conduct)
+- [How can I contribute?](#how-can-i-contribute)
+- [Using the issue tracker](#using-the-issue-tracker)
+- [Submitting a Pull Request](#submitting-a-pull-request)
+- [Coding rules](#coding-rules)
+- [Working with the code](#working-with-the-code)
+
+We also recommend that you read [How to Contribute to Open Source](https://opensource.guide/how-to-contribute).
+
+## Code of conduct
+
+Help us keep **semantic-release** open and inclusive. Please read and follow our [Code of conduct](CODE_OF_CONDUCT.md).
+
+## How can I contribute?
+
+### Improve documentation
+
+As a **semantic-release** user, you are the perfect candidate to help us improve our documentation: typo corrections, clarifications, more examples, new [recipes](docs/recipes/README.md), etc. Take a look at the [documentation issues that need help](https://github.com/issues?utf8=%E2%9C%93&q=is%3Aopen+is%3Aissue+user%3Asemantic-release+archived%3Afalse+label%3A%22help+wanted%22+label%3Adocs+).
+
+Please follow the [Documentation guidelines](#documentation).
+
+### Give feedback on issues
+
+Some issues are created without information requested in the [Bug report guideline](#bug-report). Help make them easier to resolve by adding any relevant information.
+
+Issues with the [design label](https://github.com/issues?q=is%3Aopen+is%3Aissue+user%3Asemantic-release+archived%3Afalse+label%3Adesign) are meant to discuss the implementation of new features. Participating in the discussion is a good opportunity to get involved and influence the future direction of **semantic-release**.
+
+### Fix bugs and implement features
+
+Confirmed bugs and ready-to-implement features are marked with the [help wanted label](https://github.com/issues?utf8=%E2%9C%93&q=is%3Aopen+is%3Aissue+user%3Asemantic-release+archived%3Afalse+label%3A%22help+wanted%22). Post a comment on an issue to indicate you would like to work on it and to request help from the [@semantic-release/maintainers](https://github.com/orgs/semantic-release/teams/contributors) and the community.
+
+## Using the issue tracker
+
+The issue tracker is the channel for [bug reports](#bug-report), [features requests](#feature-request) and [submitting pull requests](#submitting-a-pull-request) only. Please use the [Support](docs/support/README.md) and [Get help](README.md#get-help) sections for support, troubleshooting and questions.
+
+Before opening an issue or a Pull Request, please use the [GitHub issue search](https://github.com/issues?utf8=%E2%9C%93&q=user%3Asemantic-release) to make sure the bug or feature request hasn't been already reported or fixed.
+
+### Bug report
+
+A good bug report shouldn't leave others needing to chase you for more information. Please try to be as detailed as possible in your report and fill the information requested in the [Bug report template](https://github.com/semantic-release/semantic-release/issues/new?template=bug-report.md).
+
+### Feature request
+
+Feature requests are welcome, but take a moment to find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. Please provide as much detail and context as possible and fill the information requested in the [Feature request template](https://github.com/semantic-release/semantic-release/issues/new?template=feature-request.md).
+
+### New plugin request
+
+[Plugins](docs/usage/plugins.md) are a great way to extend **semantic-release** capabilities, integrate with other systems and support new project type. Please provide as much detail and context as possible and fill the information requested in the [New plugin request template](https://github.com/semantic-release/semantic-release/issues/new?template=plugin-request.md).
+
+## Submitting a Pull Request
+
+Good pull requests, whether patches, improvements, or new features, are a fantastic help. They should remain focused in scope and avoid containing unrelated commits.
+
+**Please ask first** before embarking on any significant pull requests (e.g. implementing features, refactoring code), otherwise you risk spending a lot of time working on something that the project's developers might not want to merge into the project.
+
+If you have never created a pull request before, welcome 🎉 😄. [Here is a great tutorial](https://opensource.guide/how-to-contribute/#opening-a-pull-request) on how to send one :)
+
+Here is a summary of the steps to follow:
+
+1. [Set up the workspace](#set-up-the-workspace)
+2. If you cloned a while ago, get the latest changes from upstream and update dependencies:
+```bash
+$ git checkout master
+$ git pull upstream master
+$ rm -rf node_modules
+$ npm install
+```
+3. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix:
+```bash
+$ git checkout -b <topic-branch-name>
+```
+4. Make your code changes, following the [Coding rules](#coding-rules)
+5. Push your topic branch up to your fork:
+```bash
+$ git push origin <topic-branch-name>
+```
+6. [Open a Pull Request](https://help.github.com/articles/creating-a-pull-request/#creating-the-pull-request) with a clear title and description.
+
+**Tips**:
+- For ambitious tasks, open a Pull Request as soon as possible with the `[WIP]` prefix in the title, in order to get feedback and help from the community.
+- [Allow semantic-release maintainers to make changes to your Pull Request branch](https://help.github.com/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork). This way, we can rebase it and make some minor changes if necessary. All changes we make will be done in new commit and we'll ask for your approval before merging them.
+
+## Coding rules
+
+### Source code
+
+To ensure consistency and quality throughout the source code, all code modifications must have:
+- No [linting](#lint) errors
+- A [test](#tests) for every possible case introduced by your code change
+- **100%** test coverage
+- [Valid commit message(s)](#commit-message-guidelines)
+- Documentation for new features
+- Updated documentation for modified features
+
+### Documentation
+
+To ensure consistency and quality, all documentation modifications must:
+- Refer to brand in [bold](https://help.github.com/articles/basic-writing-and-formatting-syntax/#styling-text) with proper capitalization, i.e. **GitHub**, **semantic-release**, **npm**
+- Prefer [tables](https://help.github.com/articles/organizing-information-with-tables) over [lists](https://help.github.com/articles/basic-writing-and-formatting-syntax/#lists) when listing key values, i.e. List of options with their description
+- Use [links](https://help.github.com/articles/basic-writing-and-formatting-syntax/#links) when you are referring to:
+  - a **semantic-release** concept described somewhere else in the documentation, i.e. How to [contribute](CONTRIBUTING.md)
+  - a third-party product/brand/service, i.e. Integrate with [GitHub](https://github.com)
+  - an external concept or feature, i.e. Create a [GitHub release](https://help.github.com/articles/creating-releases)
+  - a package or module, i.e. The [`@semantic-release/github`](https://github.com/semantic-release/github) module
+- Use the the [single backtick `code` quoting](https://help.github.com/articles/basic-writing-and-formatting-syntax/#quoting-code) for:
+  - commands inside sentences, i.e. the `semantic-release` command
+  - programming language keywords, i.e. `function`, `async`, `String`
+  - packages or modules, i.e. The [`@semantic-release/github`](https://github.com/semantic-release/github) module
+- Use the the [triple backtick `code` formatting](https://help.github.com/articles/creating-and-highlighting-code-blocks) for:
+  - code examples
+  - configuration examples
+  - sequence of command lines
+
+### Commit message guidelines
+
+#### Atomic commits
+
+If possible, make [atomic commits](https://en.wikipedia.org/wiki/Atomic_commit), which means:
+- a commit should contain exactly one self-contained functional change
+- a functional change should be contained in exactly one commit
+- a commit should not create an inconsistent state (such as test errors, linting errors, partial fix, feature with documentation etc...)
+
+A complex feature can be broken down into multiple commits as long as each one maintains a consistent state and consists of a self-contained change.
+
+#### Commit message format
+
+Each commit message consists of a **header**, a **body** and a **footer**. The header has a special format that includes a **type**, a **scope** and a **subject**:
+
+```commit
+<type>(<scope>): <subject>
+<BLANK LINE>
+<body>
+<BLANK LINE>
+<footer>
+```
+
+The **header** is mandatory and the **scope** of the header is optional.
+
+The **footer** can contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages).
+
+#### Revert
+
+If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
+
+#### Type
+
+The type must be one of the following:
+
+| Type         | Description                                                                                                 |
+|--------------|-------------------------------------------------------------------------------------------------------------|
+| **build**    | Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)         |
+| **ci**       | Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs) |
+| **docs**     | Documentation only changes                                                                                  |
+| **feat**     | A new feature                                                                                               |
+| **fix**      | A bug fix                                                                                                   |
+| **perf**     | A code change that improves performance                                                                     |
+| **refactor** | A code change that neither fixes a bug nor adds a feature                                                   |
+| **style**    | Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)      |
+| **test**     | Adding missing tests or correcting existing tests                                                           |
+
+#### Subject
+
+The subject contains succinct description of the change:
+
+- use the imperative, present tense: "change" not "changed" nor "changes"
+- don't capitalize first letter
+- no dot (.) at the end
+
+#### Body
+Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
+The body should include the motivation for the change and contrast this with previous behavior.
+
+#### Footer
+The footer should contain any information about **Breaking Changes** and is also the place to reference GitHub issues that this commit **Closes**.
+
+**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.
+
+#### Examples
+
+```commit
+`fix(pencil): stop graphite breaking when too much pressure applied`
+```
+
+```commit
+`feat(pencil): add 'graphiteWidth' option`
+
+Fix #42
+```
+
+```commit
+perf(pencil): remove graphiteWidth option`
+
+BREAKING CHANGE: The graphiteWidth option has been removed.
+
+The default graphite width of 10mm is always used for performance reasons.
+```
+
+## Working with the code
+
+### Set up the workspace
+
+[Fork](https://guides.github.com/activities/forking/#fork) the project, [clone](https://guides.github.com/activities/forking/#clone) your fork, configure the remotes and install the dependencies:
+
+```bash
+# Clone your fork of the repo into the current directory
+$ git clone https://github.com/semantic-release/<repo-name>
+# Navigate to the newly cloned directory
+$ cd <repo-name>
+# Assign the original repo to a remote called "upstream"
+$ git remote add upstream https://github.com/semantic-release/<repo-name>
+# Install the dependencies
+$ npm install
+```
+
+### Lint
+
+All the [semantic-release](https://github.com/semantic-release) repositories use [XO](https://github.com/sindresorhus/xo) for linting and [Prettier](https://prettier.io) for formatting. Prettier formatting will be automatically verified and fixed by XO.
+
+Before pushing your code changes make sure there are no linting errors with `npm run lint`.
+
+**Tips**:
+- Most linting errors can be automatically fixed with `npm run lint --fix`.
+- Install the [XO plugin](https://github.com/sindresorhus/xo#editor-plugins) for your editor to see linting errors directly in your editor and automatically fix them on save.
+
+### Tests
+
+Running the integration test requires you to install [Docker](https://docs.docker.com/engine/installation) on your machine.
+
+All the [semantic-release](https://github.com/semantic-release) repositories use [AVA](https://github.com/avajs/ava) for writing and running tests.
+
+Before pushing your code changes make sure all **tests pass** and the **coverage is 100%**:
+
+```bash
+$ npm run test
+```
+
+**Tips:** During development you can:
+- run only a subset of test files with `ava <glob>`, for example `ava test/mytestfile.test.js`
+- run in watch mode with `ava -w` to automatically run a test file when you modify it
+- run only the test you are working on by adding [`.only` to the test definition](https://github.com/avajs/ava#running-specific-tests)
+
+### Commits
+
+All the [semantic-release](https://github.com/semantic-release) repositories use [Commitizen](https://github.com/commitizen/cz-cli) to help you create [valid commit messages](#commit-message-guidelines).
+
+After staging your changes with `git add`, run `npm run cm` to start the interactive commit message CLI.

-`semantic-release` builds upon a set of conventions to give you **fully automated, semver-compliant package publishing**. It's mostly about _commit-messages_, but you can define more _heuristics_.
+## Highlights
 
-&nbsp; | Commands | Comment
---- | --- | ---
-| **manual** | <pre><code><div>npm version major</div><div>git push origin master --tags</div><div>npm publish</div></code></pre> | You **manually decide** what the **next version** is. You have to remember what major, minor and patch means. You have to remember to push both commits and tags. You have to wait for the CI to pass. |
-| **semantic-release** | <pre><code><div>git commit -m "fix: &lt;message&gt;"</div><div>git push</div></code></pre> | You **think about and describe the changes** you've made. A new version is automatically published with the correct version number.
-
-This removes the immediate connection between human emotions and version numbers, so strictly following the [SemVer](http://semver.org/) spec is not a problem anymore – and that’s ultimately `semantic-release`’s goal.

-> This talk gives you a complete introduction to the underlying concepts of this module
+- Fully automated release
+- Enforce [Semantic Versioning](https://semver.org) specification
+- New features and fixes are immediately available to users
+- Notify maintainers and users of new releases
+- Use formalized commit message convention to document changes in the codebase
+- Integrate with your [continuous integration workflow](docs/recipes/README.md#ci-configurations)
+- Avoid potential errors associated with manual releases
+- Support any [package managers and languages](docs/recipes/README.md#package-managers-and-languages) via [plugins](docs/usage/plugins.md)
+- Simple and reusable configuration via [shareable configurations](docs/usage/shareable-configurations.md)
 
 ## How does it work?
 
-Instead of writing [meaningless commit messages](http://whatthecommit.com/), we can take our time to think about the changes in the codebase and write them down. Following formalized conventions it this then possible to generate a helpful changelog and to derive the next semantic version number from them.
+### Commit message format
 
-_Note: This module ships with the [AngularJS Commit Message Conventions](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit) and changelog generator, but you can [define your own](#plugins) style_.
+**semantic-release** uses the commit messages to determine the type of changes in the codebase. Following formalized conventions for commit messages, **semantic-release** automatically determines the next [semantic version](https://semver.org) number, generates a changelog and publishes the release.
 
-> ### Commit Message Format
+By default **semantic-release** uses [Angular Commit Message Conventions](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#-git-commit-guidelines). The commit message format can be changed with the [`preset` or `config` options](docs/usage/configuration.md#options) of the [@semantic-release/commit-analyzer](https://github.com/semantic-release/commit-analyzer#options) and [@semantic-release/release-notes-generator](https://github.com/semantic-release/release-notes-generator#options) plugins.
 
-> Each commit message consists of a **header**, a **body** and a **footer**.  The header has a special
-format that includes a **type**, a **scope** and a **subject**:
+Tools such as [commitizen](https://github.com/commitizen/cz-cli), [commitlint](https://github.com/marionebl/commitlint) or [semantic-git-commit-cli](https://github.com/JPeer264/node-semantic-git-commit-cli) can be used to help contributors and enforce valid commit messages.
 
-> ```
-<type>(<scope>): <subject>
-<BLANK LINE>
-<body>
-<BLANK LINE>
-<footer>
-```
+Here is an example of the release type that will be done based on a commit messages:

+| Commit message                                                                                                                                                                                   | Release type               |

+| `feat(pencil): add 'graphiteWidth' option`                                                                                                                                                       | ~~Minor~~ Feature Release  |
+| `perf(pencil): remove graphiteWidth option`<br><br>`BREAKING CHANGE: The graphiteWidth option has been removed.`<br>`The default graphite width of 10mm is always used for performance reasons.` | ~~Major~~ Breaking Release |
 
-When `semantic-release` got setup it will do that after every successful continuous integration build of your master branch (or any other branch you specify) and publish the new version for you. That way no human is directly involved in the release process and your releases are guaranteed to be [unromantic and unsentimental](http://sentimentalversioning.org/).
+### Automation with CI
 
-If you fear the loss of control over timing and marketing implications of software releases you should know that `semantic-release` supports [release channels](https://github.com/npm/npm/issues/2718) using `npm`'s [dist-tags](https://docs.npmjs.com/cli/tag). This way you can keep control over what your users end up using by default, you can decide when to promote an automatically released version to the stable channel and you can choose which versions to write blogposts and tweets about. You can use the same mechanism to support older versions of your software, for example with important security fixes.
+**semantic-release** is meant to be executed on the CI environment after every successful build on the release branch. This way no human is directly involved in the release process and the releases are guaranteed to be [unromantic and unsentimental](http://sentimentalversioning.org).
 
-This is what happens in series:
+### Triggering a release
 
-| 1. `git push` | 2. `semantic-release pre` | 3. `npm publish` | 4. `semantic-release post` |
-| :--- | :--- | :--- | :---- |
-| New code is pushed and triggers a CI build. | Based on all commits that happened since the last release, the new version number gets written to the `package.json`. | The new version gets published to `npm`. | A changelog gets generated and a [release](https://help.github.com/articles/about-releases/) (including a git tag) on GitHub gets created. |
+When pushing new commits to the release branch (i.e. `master`) with `git push` or by merging a pull request or merging from another branch, a CI build is triggered and runs the `semantic-release` command to make a release if there are relevant codebase changes since the last release.
 
-_Note:_ The current release/tag implementation is tied to GitHub, but could be opened up to Bitbucket, GitLab, et al. Feel free to send PRs for these services.
+By default a release will be done for each push to the release branch that contains relevant code changes. If you need more control over the timing of releases you have a couple of options:
+- Publish releases on a distribution channel (for example npm’s [dist-tags](https://docs.npmjs.com/cli/dist-tag)). This way you can keep control over what your users end up using by default, and you can decide when to make an automatically released version available to the stable channel, and promote it.
+- Develop on a `dev` branch and merge it to the release branch (i.e. `master`) once you are ready to publish. **semantic-release** will run only on pushes to the release branch.

-## Options
-
-You can pass options either via command line (in [kebab-case](https://lodash.com/docs#kebabCase)) or in the `release` field of your `package.json` (in [camelCase](https://lodash.com/docs#camelCase)). The following two examples are the same, but CLI arguments take precedence.
-
-| CLI | package.json |
-| --- | --- |
-| <pre><code>semantic-release pre --no-debug</code><pre> | <pre><code><div>//package.json</div><div>"release": {</div><div>  "debug": false</div><div>}</div></code></pre><pre><code>semantic-release pre</code></pre> |
-
-
-These options are currently available:
-- `branch`: The branch on which releases should happen. Default: `'master'`
-- `debug`: If true doesn't actually publish to npm or write things to file. Default: `!process.env.CI`
-- `githubToken`: The token used to authenticate with GitHub. Default: `process.env.GH_TOKEN`
-- `githubUrl`: Optional. Pass your GitHub Enterprise endpoint.
-
-_A few notes on `npm` config_:
-1. The `npm` token can only be defined in the environment as `NPM_TOKEN`, because that's where `npm` itself is going to read it from.
-
-2. In order to publish to a different `npm` registry you can just configure that how you would usually do it and `semantic-release` will respect that setting.
-
-3. If you want to use another dist-tag for your publishes than `'latest'` you can specify that inside the `package.json`'s [`publishConfig`](https://docs.npmjs.com/files/package.json#publishconfig) field.
-
-4. `semantic-release` generally tries to orientate itself towards `npm` – it inherits the loglevel for example.
-
-## Plugins
-
-There are numerous steps where you can customize `semantic-release`'s behaviour using plugins. A plugin is a regular [option](#options), but passed inside the `release` block of `package.json`:
-
-```json
-{
-  "release": {
-    "analyzeCommits": "npm-module-name",
-    "generateNotes": "./path/to/a/local/module",
-    "verifyConditions": {
-      "path": "./path/to/a/module",
-      "additional": "config"
-    }
-}
-```
-
-```
-semantic-release pre --analyze-commits="npm-module-name"
-```
-
-A plugin itself is an async function that always receives three arguments.
-
-```js
-module.exports = function (pluginConfig, config, callback) {}
-```
-
-- `pluginConfig`: If the user of your plugin specifies additional plugin config in the `package.json` (see the `verifyConditions` example above) then it's this object.
-- `config`: A config object containing a lot of information to act upon.
-  - `env`: All environment variables
-  - `npm`: Select npm configuration bits like `registry`, `tag` and `auth`
-  - `options`: `semantic-release` options like `debug`, or `branch`
-  - `pkg`: Parsed `package.json`
-  - For certain plugins the `config` object contains even more information. See below.
-- `callback`: If an error occurs pass it as first argument. Otherwise pass your result as second argument.
-
-
-### `analyzeCommits`
-
-This plugin is responsible for determining the type of the next release. It additionally receives a `commits` array inside `config`. One commit is an object with a `message` and `hash` property. Call the callback with `'major'`, `'premajor'`, `'minor'`, `'preminor'`, `'patch'`, `'prepatch'`, `'prerelease'`, or `null` if nothing changed. Have a look at the [default implementation](https://github.com/semantic-release/commit-analyzer/).
-
-### `generateNotes`
-
-This plugin is responsible for generating release notes. Call the callback with the notes as a string. Have a look at the [default implementation](https://github.com/semantic-release/release-notes-generator/).
-
-### `verifyConditions`
-
-This plugins is responsible for verifying that a release should happen in the first place. For example, the [default implementation](https://github.com/semantic-release/condition-travis/) verifies that the publish is happening on Travis, that it's the right branch, and that all other build jobs succeeded. There are more use cases for this, e.g. verifying that test coverage is above a certain threshold or that there are no [vulnerabilities](https://nodesecurity.io/) in your dependencies. Be creative.
-
-Passing an array of plugins will run them in series.
-
-### `verifyRelease`
-
-This plugin is responsible for verifying a release that was determined before and is about to be published. There is no default implementation. It additionally receives `nextRelease`, `lastRelease` and `commits` inside `config`. While `commits` is the same as with analyzeCommits, `nextRelease` contains a `type` (e.g. `'major'`) and the new version (e.g. `'1.0.0'`) and `lastRelease` contains the old `version`, the `gitHead` at the time of the release and the npm dist-`tag` (e.g. `'latest'`). Using this information you could [detect breaking changes](https://github.com/semantic-release/cracks) or hold back certain types of releases. Again: Be creative.
-
-Passing an array of plugins will run them in series.
-
-### `getLastRelease`
-
-This plugin is responsible for determining a package's last release version. The [default implementation](https://github.com/semantic-release/last-release-npm) uses the last published version on a npm registry.
-
-## ITYM*FAQ*LT
-> I think you might frequently ask questions like these
-
-### Why is the `package.json`'s version not updated in my repository?
-
-The `npm` docs even state:
-
-> The most important things in your package.json are the name and version fields. Those are actually required, and your package won't install without them.
-> – [npm docs](https://docs.npmjs.com/files/package.json#version)
-
-While this entirely true the version number doesn't have to be checked into source control. `semantic-release` takes care of the version field right before `npm publish` uses it – and this is the only point where it _really_ is required.
-
-### Is there a way to preview which version would currently get published?
-
-If you run `npm run semantic-release` locally a dry run gets performed, which logs the version that would currently get published.
-
-### Can I run this on my own machine rather than on a CI server?
-
-Of course you can, but this doesn't necessarily mean you should. Running your tests on an independent machine before releasing software is a crucial part of this workflow. Also it is a pain to set this up locally, with tokens lying around and everything. That said, you can run the scripts with `--debug=false` explicitly. You have to export `GH_TOKEN=<your_token>` and `NPM_TOKEN=<your_other_token>`.
-
-### Can I manually trigger the release of a specific version?
-
-You can trigger a release by pushing to your GitHub repository. You deliberately cannot trigger a _specific_ version release, because this is the whole point of `semantic-release`. Start your packages with `1.0.0` and semver on.  
-
-### Is it _really_ a good idea to release on every push?
-
-It is indeed a great idea because it _forces_ you to follow best practices. If you don't feel comfortable making every passing feature or fix on your master branch addressable via `npm` you might not treat your master right. Have a look at [branch workflows](https://guides.github.com/introduction/flow/index.html). If you still think you should have control over the exact point in time of your release, e.g. because you are following a release schedule, you can release only on the `production`/`deploy`/`release` branch and push your code there in certain intervals, or better yet use [dist-tags](https://docs.npmjs.com/cli/dist-tag).
-
-### Why should I trust `semantic-release` with my releases?
-
-`semantic-release` has a full unit- and integration-test-suite that tests _actual_ `npm` publishes against the [npm-registry-couchapp](https://github.com/npm/npm-registry-couchapp/) on node.js `^0.10`, `^0.12` and io.js `^1`, `^2`. A new version won't get published if it doesn't pass on all these engines.
-
-Note: Currently integration-tests don't run on Travis CI. If you know stuff about npm/Travis/Couch: Please help!

+
+## Environment variables
+
+The [Authentication](../usage/ci-configuration.md#authentication) environment variables can be configured in [CircleCi Project Settings](https://circleci.com/docs/2.0/env-vars/#adding-environment-variables-in-the-app)..
+
+Alternatively, the default `NPM_TOKEN` and `GH_TOKEN` can be easily [setup with semantic-release-cli](../usage/ci-configuration.md#automatic-setup-with-semantic-release-cli).
+
+## Multiple Node jobs configuration
+
+### `.circleci/config.yml` configuration for multiple Node jobs
+
+This example is a minimal configuration for **semantic-release** with a build running Node 6 and 8. See [CircleCI documentation](https://circleci.com/docs/2.0) for additional configuration options.
+
+This example create the workflows `test_node_4`, `test_node_6`, `test_node_8` and `release`. The release workflows will [run `semantic-release` only after the all the `test_node_*` are successful](../usage/ci-configuration.md#run-semantic-release-only-after-all-tests-succeeded).
+
+```yaml
+version: 2
+jobs:
+  test_node_6:
+    docker:
+      - image: circleci/node:6
+    steps:
+      # Configure your test steps here (checkout, npm install, cache management, tests etc...)

+            - test_node_8
+```
+

+# Git authentication with SSH keys
+
+When using [environment variables](../usage/ci-configuration.md#authentication) to set up the Git authentication, the remote Git repository will automatically be accessed via [https](https://git-scm.com/book/en/v2/Git-on-the-Server-The-Protocols#_the_http_protocols), independently of the [`repositoryUrl`](../usage/configuration.md#repositoryurl) format configured in the **semantic-release** [Configuration](../usage/configuration.md#configuration) (the format will be automatically converted as needed).
+
+Alternatively the Git repository can be accessed via [SSH](https://git-scm.com/book/en/v2/Git-on-the-Server-The-Protocols#_the_ssh_protocol) by creating SSH keys, adding the public one to your Git hosted account and making the private one available on the CI environment.
+
+**Note:** SSH keys allow to push the [Git release tag](https://git-scm.com/book/en/v2/Git-Basics-Tagging) associated to the released version. Some plugins might also require an API token. See each plugin documentation for additional information.
+
+## Generating the SSH keys
+
+In your local repository root:
+
+```bash
+$ ssh-keygen -t rsa -b 4096 -C "<your_email>" -f git_deploy_key -N "<ssh_passphrase>"
+```
+
+`your_email` must be the email associated with your Git hosted account. `ssh_passphrase` must be a long and hard to guess string. It will be used later.
+
+This will generate a public key in `git_deploy_key.pub` and a private key in `git_deploy_key`.
+
+## Adding the SSH public key to the Git hosted account
+
+Step by step instructions are provided for the following Git hosted services:
+- [GitHub](#adding-the-ssh-public-key-to-github)
+
+### Adding the SSH public key to GitHub
+
+Open the `git_deploy_key.pub` file (public key) and copy the entire content.
+
+In GitHub **Settings**, click on **SSH and GPG keys** in the sidebar, then on the **New SSH Key** button.
+
+Paste the entire content of `git_deploy_key.pub` file (public key) and click the **Add SSH Key** button.
+
+Delete the `git_deploy_key.pub` file:
+
+```bash
+$ rm git_deploy_key.pub
+```
+
+See [Adding a new SSH key to your GitHub account](https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/) for more details.
+
+## Adding the SSH private key to the CI environment
+
+In order to be available on the CI environment, the SSH private key must be encrypted, committed to the Git repository and decrypted by the CI service.
+
+Step by step instructions are provided for the following environments:
+- [Travis CI](#adding-the-ssh-private-key-to-travis-ci)
+- [Circle CI](#adding-the-ssh-private-key-to-circle-ci)
+
+### Adding the SSH private key to Travis CI
+
+Install the [Travis CLI](https://github.com/travis-ci/travis.rb#installation):
+
+```bash
+$ gem install travis
+```
+
+[Login](https://github.com/travis-ci/travis.rb#login) to Travis with the CLI:
+
+```bash
+$ travis login
+```
+
+Add the [environment](https://github.com/travis-ci/travis.rb#env) variable `SSH_PASSPHRASE` to Travis with the value set during the [SSH keys generation](#generating-the-ssh-keys) step:
+
+```bash
+$ travis env set SSH_PASSPHRASE <ssh_passphrase>
+```
+
+[Encrypt](https://github.com/travis-ci/travis.rb#encrypt) the `git_deploy_key` (private key) using a symmetric encryption (AES-256), and store the secret in a secure environment variable in the Travis environment:
+
+```bash
+$ travis encrypt-file git_deploy_key
+```
+
+The `travis encrypt-file` will encrypt the private key into the `git_deploy_key.enc` file and output in the console the command to add to your `.travis.yml` file. It should look like `openssl aes-256-cbc -K $encrypted_KKKKKKKKKKKK_key -iv $encrypted_VVVVVVVVVVVV_iv -in git_deploy_key.enc -out git_deploy_key -d`.
+
+Copy this command to your `.travis.yml` file in the `before_install` step. Change the output path to write the unencrypted key in `/tmp`: `-out git_deploy_key` => `/tmp/git_deploy_key`. This will avoid to commit / modify / delete the unencrypted key by mistake on the CI. Then add the commands to decrypt the ssh private key and make it available to `git`:
+
+```yaml
+before_install:
+  # Decrypt the git_deploy_key.enc key into /tmp/git_deploy_key
+  - openssl aes-256-cbc -K $encrypted_KKKKKKKKKKKK_key -iv $encrypted_VVVVVVVVVVVV_iv -in git_deploy_key.enc -out /tmp/git_deploy_key -d
+  # Make sure only the current user can read the private key
+  - chmod 600 /tmp/git_deploy_key
+  # Create a script to return the passphrase environment variable to ssh-add
+  - echo 'echo ${SSH_PASSPHRASE}' > /tmp/askpass && chmod +x /tmp/askpass
+  # Start the authentication agent
+  - eval "$(ssh-agent -s)"
+  # Add the key to the authentication agent
+  - DISPLAY=":0.0" SSH_ASKPASS="/tmp/askpass" setsid ssh-add /tmp/git_deploy_key </dev/null
+```
+
+See [Encrypting Files](https://docs.travis-ci.com/user/encrypting-files) for more details.
+
+Delete the local private key as it won't be used anymore:
+
+```bash
+$ rm git_deploy_key
+```
+
+Commit the encrypted private key and the `.travis.yml` file to your repository:
+
+```bash
+$ git add git_deploy_key.enc .travis.yml
+$ git commit -m "ci(travis): Add the encrypted private ssh key"
+$ git push
+```
+
+### Adding the SSH private key to Circle CI
+
+First we encrypt the `git_deploy_key` (private key) using a symmetric encryption (AES-256).  Run the following `openssl` command and *make sure to note the output which we'll need later*:
+
+```bash
+$ openssl aes-256-cbc -e -p -in git_deploy_key -out git_deploy_key.enc -K `openssl rand -hex 32` -iv `openssl rand -hex 16`
+salt=SSSSSSSSSSSSSSSS
+key=KKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK
+iv =VVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVV
+```
+
+Add the following [environment variables](https://circleci.com/docs/2.0/env-vars/#adding-environment-variables-in-the-app) to Circle CI:
+- `SSL_PASSPHRASE` - the value set during the [SSH keys generation](#generating-the-ssh-keys) step.
+- `REPO_ENC_KEY` - the `key` (KKK) value from the `openssl` step above.
+- `REPO_ENC_IV` - the `iv` (VVV) value from the `openssl` step above.
+
+Then add to your `.circleci/config.yml` the commands to decrypt the ssh private key and make it available to `git`:
+

+
+## Node project configuration
+
+GitLab CI supports [Pipelines](https://docs.gitlab.com/ee/ci/pipelines.html) allowing to test on multiple Node versions and publishing a release only when all test pass.
+
+**Note**: The publish pipeline must run a [Node >= 8 version](../support/FAQ.md#why-does-semantic-release-require-node-version--83).
+
+### `.gitlab-ci.yml` configuration for Node projects
+
+This example is a minimal configuration for **semantic-release** with a build running Node 6 and 8. See [GitLab CI - Configuration of your jobs with .gitlab-ci.yml](https://docs.gitlab.com/ee/ci/yaml/README.html) for additional configuration options.
+
+**Note**: The`semantic-release` execution command varies depending if you are using a [local](../usage/installation.md#local-installation) or [global](../usage/installation.md#global-installation) **semantic-release** installation.
+
+```yaml
+# The release pipeline will run only if all jobs in the test pipeline are successful

+
+**Advanced configuration**: Running the tests in the `script` step of the `release` stage is not necessary as the previous stage(s) already ran them. To increase speed, the `script` step of the `release` stage can be overwritten to skip the tests. Note that other commands such as build or compilation might still be required.

+# Frequently Asked Questions
+
+## Why is the `package.json`’s version not updated in my repository?
+
+**semantic-release** takes care of updating the `package.json`’s version before publishing to [npm](https://www.npmjs.com).
+
+By default, only the published package will contains the version, which is the only place where it is *really* required, but the updated `package.json` will not be pushed to the Git repository
+
+However, the [`@semantic-release/git`](https://github.com/semantic-release/git) plugin can be used to push the updated `package.json` as well as other files to the Git repository.
+
+## How can I use a npm build script that requires the `package.json`’s version ?
+
+The `package.json`’s version will be updated by the `semantic-release` command just before publishing to [npm](https://www.npmjs.com), therefore it won't be available for scripts ran before the `semantic-release` command.
+
+As semantic-release uses the [npm CLI](https://docs.npmjs.com/cli/npm) to publish, all [npm hook scripts](https://docs.npmjs.com/misc/scripts#hook-scripts) will be executed. Therefore you can run your build script in the [`prepublishOnly`](https://docs.npmjs.com/misc/scripts#prepublish-and-prepare) hook. It will be executed after the `semantic-release` command update the `package.json`’s version and before publishing.
+
+## Is there a way to preview which version would currently get published?
+
+Yes with the [dry-run options](../usage/configuration.md#dryrun) which prints to the console the next version to be published and the release notes.
+
+## Can I use semantic-release with Yarn?
+
+If you are using a [local](../usage/installation.md#local-installation) **semantic-release** installation and run multiple CI jobs with different versions, the `yarn install` command will fail on jobs running with Node < 8 as **semantic-release** requires [Node >= 8.3](#why-does-semantic-release-require-node-version--83) and specifies it in its `package.json`s [`engines`](https://docs.npmjs.com/files/package.json#engines) key.
+
+The recommended solution is to use the [Yarn](https://yarnpkg.com) [--ignore-engines](https://yarnpkg.com/en/docs/cli/install#toc-yarn-install-ignore-engines) option to install the project dependencies on the CI environment, so Yarn will ignore the **semantic-release**'s `engines` key:
+
+```bash
+$ yarn install --ignore-engines
+```
+
+**Note**: Several CI services use Yarn by default if your repository contains a `yarn.lock` file. So you should override the install step to specify `yarn install --ignore-engines`.
+
+Alternatively you can use a [global](../usage/installation.md#global-installation) **semantic-release** installation and make sure to install and run the `semantic-release` command only in a CI jobs running with Node >= 8.3.
+
+If your CI environment provides [nvm](https://github.com/creationix/nvm) you can switch to Node 8 before installing and running the `semantic-release` command:
+
+```bash
+$ nvm install 8 && yarn global add semantic-release && semantic-release
+```
+
+See the [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on specific CI environments.
+
+As `semantic-release` is recommended to be executed with [`npx`](https://www.npmjs.com/package/npx) an alternative is required for usage with Yarn. Even though it is possible to install npx with Yarn, it's not recommended. Yarn and npx would be using different cache locations.
+
+For [local installation](../usage/installation.md#local-installation) replace
+`npx semantic-release` with `yarn run semantic-release`.
+
+For [global installation](../usage/installation.md#global-installation) replace
+`npx semantic-release` with `yarn global add semantic-release && semantic-release`.
+
+## Can I use semantic-release to publish non-JavaScript packages?
+
+Yes, **semantic-release** is a Node CLI application but it can be used to publish any type of packages.
+
+To publish a non-Node package (without a `package.json`) you would need to:
+- Use a [global](../usage/installation.md#global-installation) **semantic-release** installation
+- Set **semantic-release** [options](../usage/configuration.md#options) via [CLI arguments or rc file](../usage/configuration.md#configuration)
+- Make sure your CI job executing the `semantic-release` command has access to [Node >= 8](#why-does-semantic-release-require-node-version--83) to execute the `semantic-release` command
+
+See the [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on specific CI environments.
+
+In addition you will need to configure the **semantic-release** [plugins](../usage/plugins.md#plugins) to:
+- Disable the [`@semantic-release/npm`](https://github.com/semantic-release/npm) plugin
+- Define plugins for the [verifyConditions](../usage/plugins.md#verifyconditions-plugin), [prepare](../usage/plugins.md#prepare-plugin) and [publish](../usage/plugins.md#publish-plugin) steps to release on your package registry. The [`@semantic-release/exec`](https://github.com/semantic-release/exec) plugin is recommended for situation where a release can be done with a shell command.
+
+Here is a basic example to create [GitHub releases](https://help.github.com/articles/about-releases) and use shell command to publish:
+
+```json
+{
+  "verifyConditions": ["@semantic-release/github"],
+  "prepare": [
+    {
+      "path": "@semantic-release/exec",
+      "cmd": "set-version ${nextRelease.version}"
+    }
+  ],
+  "publish": [
+    "@semantic-release/github",
+    {
+      "path": "@semantic-release/exec",
+      "cmd": "publish-package"
+    }
+  ],
+}
+```
+
+**Note**: This is a theoretical example where the command `set-version` update the project version with the value passed as its first argument and `publish-package` publishes the package to a registry.
+
+See the [package managers and languages recipes](../recipes/README.md#package-managers-and-languages) for more details on specific project types.
+
+## Can I use semantic-release with any CI service?
+
+Yes, **semantic-release** can be used with any CI service, as long as it provides:
+- A way to set [authentication](../usage/ci-configuration.md#authentication) via environment variables
+- A way to guarantee that the `semantic-release` command is [executed only after all the tests of all the jobs in the CI build pass](../usage/ci-configuration.md#run-semantic-release-only-after-all-tests-succeeded)
+
+See the [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on specific CI environments.
+
+## Can I run semantic-release on my local machine rather than on a CI server?
+
+Yes, you can by explicitly setting the [`--no-ci` CLI option](../usage/configuration.md#options) option. You will also have to set the required [authentication](../usage/ci-configuration.md#authentication) via environment variables on your local machine, for example:
+
+```bash
+$ NPM_TOKEN=<your_npm_token> GH_TOKEN=<your_github_token> npx semantic-release --no-ci
+```
+
+However this is not the recommended approach, as running unit and integration tests on an independent machine before publishing software is a crucial part of the release workflow.
+
+## Can I use semantic-release with GitLab?
+
+Yes, with the [`@semantic-release/gitlab-config`](https://github.com/semantic-release/gitlab-config) shareable configuration.
+
+See the [GitLab CI recipes](../recipes/gitlab-ci.md#using-semantic-release-with-gitlab-ci) for the CI configuration.
+
+## Can I use semantic-release with any Git hosted environment?
+
+By default **semantic-release** uses the [`@semantic-release/github`](https://github.com/semantic-release/github) plugin to publish a [GitHub release](https://help.github.com/articles/about-releases). For other Git hosted environment the  [`@semantic-release/git`](https://github.com/semantic-release/git) and [`@semantic-release/changelog`](https://github.com/semantic-release/changelog) plugins can be used via [plugins configuration](../usage/plugins.md#configuration).
+
+See the [`@semantic-release/git`](https://github.com/semantic-release/git#semantic-releasegit) [`@semantic-release/changelog`](https://github.com/semantic-release/changelog#semantic-releasechangelog) plugins documentation for more details.
+
+## Can I skip the release to the npm registry?
+
+Yes, the publishing to the npm registry can be disabled with the [`npmPublish`](https://github.com/semantic-release/npm#options) option of the [`@semantic-release/npm`](https://github.com/semantic-release/npm) plugin. In addition the [`tarballDir`](https://github.com/semantic-release/npm#options) option allow to generate the package tarball in order to publish it to your repository with the [`@semantic-release/git`](https://github.com/semantic-release/git) or to a [GitHub release](https://help.github.com/articles/about-releases) with the [`@semantic-release/github`](https://github.com/semantic-release/github) plugin.
+
+See the [`@semantic-release/npm`](https://github.com/semantic-release/npm#semantic-releasenpm) plugin documentation for more details.
+
+## Can I use `.npmrc` options?
+
+Yes, all the [npm configuration options](https://docs.npmjs.com/misc/config) are supported via the [`.npmrc`](https://docs.npmjs.com/files/npmrc) file at the root of your repository.
+
+See the [`@semantic-release/npm`](https://github.com/semantic-release/npm#npm-configuration) plugin documentation for more details.
+
+## How can I set the access level of the published npm package?
+
+The [npm `access` option](https://docs.npmjs.com/misc/config#access) can be set in the [`.npmrc`](https://docs.npmjs.com/files/npmrc) file at the root of your repository:
+
+```rc
+access=public
+```
+
+Or with the `publishConfig.access` key in your project's `package.json`:
+
+```json
+{
+  "publishConfig": {
+    "access": "public"
+  }
+}
+```
+
+## Can I use semantic-release to publish a package on Artifactory?
+
+Any npm compatible registry is supported with the [`@semantic-release/npm`](https://github.com/semantic-release/npm) plugin. For Artifactory versions prior to 5.4, the legacy authentication has to be used (with `NPM_USERNAME`, `NPM_PASSWORD` and `NPM_EMAIL` [environment variables](https://github.com/semantic-release/npm#environment-variables)).
+
+See [npm registry authentication](https://github.com/semantic-release/npm#npm-registry-authentication) for more details.
+
+See [Artifactory - npm Registry](https://www.jfrog.com/confluence/display/RTF/Npm+Registry#NpmRegistry-AuthenticatingthenpmClient) documentation for Artifactiry configuration.
+
+## Can I manually trigger the release of a specific version?
+
+You can trigger a release by pushing to your Git repository. You deliberately cannot trigger a *specific* version release, because this is the whole point of semantic-release.
+
+## Can I exclude commits from the analysis?
+
+Yes, every commits that contains `[skip release]` or `[release skip]` in their message will be excluded from the commit analysis and won't participate in the release type determination.
+
+## Is it *really* a good idea to release on every push?
+
+It is indeed a great idea because it *forces* you to follow best practices. If you don’t feel comfortable releasing every feature or fix on your `master` you might not treat your `master` branch as intended.
+
+From [Understanding the GitHub Flow](https://guides.github.com/introduction/flow/index.html):
+
+> Branching is a core concept in Git, and the entire GitHub Flow is based upon it. There's only one rule: anything in the master branch is always deployable.
+
+If you need more control over the timing of releases, see [Triggering a release](../../README.md#triggering-a-release) for different options.
+
+## Can I set the initial release version of my package to `0.0.1`?
+
+This is not supported by **semantic-release** as it's not considered a good practice, mostly because [Semantic Versioning](https://semver.org) rules applies differently to major version zero.
+
+In early development phase when your package is not ready for production yet we recommend to publish releases on a distribution channel (for example npm’s [dist-tags](https://docs.npmjs.com/cli/dist-tag)) or to develop on a `dev` branch and merge it to `master` periodically. See [Triggering a release](../../README.md#triggering-a-release) for more details on those solutions.
+
+See [“Introduction to SemVer” - Irina Gebauer](https://blog.greenkeeper.io/introduction-to-semver-d272990c44f2) for more details on [Semantic Versioning](https://semver.org) and the recommendation to start at version `1.0.0`.
+
+## Can I trust semantic-release with my releases?
+
+**semantic-release** has a full unit and integration test suite that tests `npm` publishes against the [npm-registry-couchapp](https://github.com/npm/npm-registry-couchapp).
+
+In addition the [verify conditions step](../../README.md#release-steps) verifies that all necessary conditions for proceeding with a release are met, and a new release will be performed [only if all your tests pass](../usage/ci-configuration.md#run-semantic-release-only-after-all-tests-succeeded).
+
+## Why does semantic-release require Node version >= 8.3?
+
+**semantic-release** is written using the latest [ECMAScript 2017](https://www.ecma-international.org/publications/standards/Ecma-262.htm) features, without transpilation which **requires Node version 8.3 or higher**.
+
+See [Node version requirement](../support/node-version.md#node-version-requirement) for more details and solutions.
+
+# What is npx?
+
+[`npx`](https://www.npmjs.com/package/npx) – short for "npm exec" – is a CLI to find and execute npm binaries within the local `node_modules` folder or in the $PATH. If a binary can't be located npx will download the required package and execute it from its cache location.
+The tool is bundled with [npm](https://www.npmjs.com/package/npm) >= 5.2, or can be installed via `npm install -g npx`.
+For more details and motivation read the [introductory blog post](https://medium.com/@maybekatz/introducing-npx-an-npm-package-runner-55f7d4bd282b) by [@zkat](https://github.com/zkat).

+# Node Support Policy
+
+We only support [Long-Term Support](https://github.com/nodejs/Release) versions of Node starting with [Node 8.9.0 (LTS)](https://nodejs.org/en/blog/release/v8.9.0).
+
+We specifically limit our support to LTS versions of Node, not because this package won't work on other versions, but because we have a limited amount of time, and supporting LTS offers the greatest return on that investment.
+
+It's possible this package will work correctly on newer versions of Node. It may even be possible to use this package on older versions of Node, though that's more unlikely as we'll make every effort to take advantage of features available in the oldest LTS version we support.
+
+As each Node LTS version reaches its end-of-life we will remove that version from the node engines property of our package's package.json file. Removing a Node version is considered a breaking change and will entail the publishing of a new major version of this package. We will not accept any requests to support an end-of-life version of Node. Any merge requests or issues supporting an end-of-life version of Node will be closed.
+
+We will accept code that allows this package to run on newer, non-LTS, versions of Node. Furthermore, we will attempt to ensure our own changes work on the latest version of Node. To help in that commitment, our continuous integration setup runs against all LTS versions of Node in addition the most recent Node release; called current.
+
+JavaScript package managers should allow you to install this package with any version of Node, with, at most, a warning if your version of Node does not fall within the range specified by our node engines property. If you encounter issues installing this package, please report the issue to your package manager.

+# Node version requirement
+
+**semantic-release** is written using the latest [ECMAScript 2017](https://www.ecma-international.org/publications/standards/Ecma-262.htm) features, without transpilation which requires **requires Node version 8.3 or higher**.
+
+**semantic-release** is meant to be used in a CI environment as a development support tool, not as a production dependency. Therefore the only constraint is to run the `semantic-release` in a CI environment providing Node 8 or higher.
+
+See our [Node Support Policy](node-support-policy.md) for our long-term promise regarding Node version support.
+
+## Recommended solution
+
+### Run at least one CI job with Node >= 8.3
+
+The recommended approach is to run the `semantic-release` command from a CI job running on Node 8.3 or higher. This can either be a job used by your project to test on Node >= 8.3 or a dedicated job for the release steps.
+
+See [CI configuration](../usage/ci-configuration.md) and [CI configuration recipes](../recipes/README.md#ci-configurations) for more details.
+
+## Alternative solutions
+
+### Use `npx`
+
+`npx` is included with npm >= 5.2 and can be used to download the latest [Node 8 package published on npm](https://www.npmjs.com/package/node). Use it to execute the `semantic-release` command.
+
+```bash
+$ npx -p node@8 -c "npx semantic-release"
+```
+
+**Note:**: See [What is npx](./FAQ.md#what-is-npx) for more details.
+
+### Use `nvm`
+
+If your CI environment provides [nvm](https://github.com/creationix/nvm) you can use it to switch to Node 8 before running the `semantic-release` command.
+
+```bash
+$ nvm install 8 && npx semantic-release
+```

+# Troubleshooting
+
+## ENOTINHISTORY Commit not in history
+
+This error happens when the commit associated with the last release cannot be found in the branch history.
+
+Multiple situation can cause this issue:
+- The package name configured in your `package.json` already exists and **semantic-release** obtains the last release of that package, which is unrelated to yours
+- The commit history has been rewritten since the last release (with `git rebase` and `git push -f`)
+
+If the package name configured in your `package.json` already exits, you should change it, and commit the `package.json`. Then **semantic-release** will proceed normally and make the initial release.
+
+If you can identify the commit in your branch history that should be associated with the release version mentioned in the error message you can recover by tagging this commit:
+
+```bash
+$ git tag -f v<version of the last release> <commit sha1 corresponding to last release>
+$ git push -f --tags origin <your release branch>
+```
+
+## ENOGITHEAD There is no commit associated with last release
+
+This error happens when there is no commit associated with the last release that can be found in the package metadata on the npm registry.
+
+This usually happen when the last release has been made without access to the git repository informations.
+
+You can recover from that issue by identifying the commit in your branch history that should have been associated with the release version mentioned in the error message and tagging this commit:
+
+```bash
+$ git tag -f v<version of the last release> <commit sha1 corresponding to last release>
+$ git push -f --tags origin <your release branch>
+```
+
+## You do not have permission to publish 'package-name'
+
+When running semantic-release you may encounter the following error:
+
+```
+An error occurred while running semantic-release: { Error: Command failed: npm publish ./. --registry https://registry.npmjs.org/
+npm ERR! publish Failed PUT 403
+npm ERR! code E403
+npm ERR! You do not have permission to publish "<package-name>". Are you logged in as the correct user? : <package-name>
+```
+
+This message is a little unclear, and might not have anything to with your `NPM_TOKEN` or authentication method. It might instead be related to the package name itself. If there is already a package with the same name as yours or, there is a very close match, it could trigger this error.
+
+Best way to be sure, is to search [npmjs.org](https://www.npmjs.com/)) using your package name. If there is a name conflict, rename your package in your `package.json`

+# CI configuration
+
+## Run `semantic-release` only after all tests succeeded
+
+The `semantic-release` command must be executed only after all the tests in the CI build pass. If the build runs multiple jobs (for example to test on multiple Operating Systems or Node versions) the CI has to be configured to guarantee that the `semantic-release` command is executed only after all jobs are successful. This can be achieved with [Travis Build Stages](https://docs.travis-ci.com/user/build-stages), [CircleCI Workflows](https://circleci.com/docs/2.0/workflows), [Codeship Deployment Pipelines](https://documentation.codeship.com/basic/builds-and-configuration/deployment-pipelines), [GitLab Pipelines](https://docs.gitlab.com/ee/ci/pipelines.html#introduction-to-pipelines-and-jobs), [Wercker Workflows](http://devcenter.wercker.com/docs/workflows), [GoCD Pipelines](https://docs.gocd.org/current/introduction/concepts_in_go.html#pipeline) or specific tools like [`travis-deploy-once`](https://github.com/semantic-release/travis-deploy-once).

+
+## Authentication
+
+**semantic-release** requires push access to the project Git repository in order to create [Git tags](https://git-scm.com/book/en/v2/Git-Basics-Tagging). The Git authentication can be set with one of the following environment variables:
+
+| Variable                        | Description                                                                                                                   |
+|---------------------------------|-------------------------------------------------------------------------------------------------------------------------------|

+| `GIT_CREDENTIALS`               | [URL encoded basic HTTP Authentication](https://en.wikipedia.org/wiki/Basic_access_authentication#URL_encoding) credentials). |
+
+`GIT_CREDENTIALS` must be the Git username and password in the format `<username>:<password>`.
+
+Alternatively the Git authentication can be set up via [SSH keys](../recipes/git-auth-ssh-keys.md).
+
+Most **semantic-release** [plugins](plugins.md) require setting up authentication in order to publish to a package manager registry. The default [@semantic-release/npm](https://github.com/semantic-release/npm#environment-variables) and [@semantic-release/github](https://github.com/semantic-release/github#environment-variables) plugins require the following environment variables:

+| `GH_TOKEN`  | GitHub authentication token.<br/>**Note**: Only the [personal token](https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line) authentication is supported.                                                                                                                                 |
+
+See each plugin documentation for the environment variables to set up.
+
+The authentication token/credentials have to be made available in the CI service via environment variables.
+
+See [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on how to configure environment variables in your CI service.
+
+## Automatic setup with `semantic-release-cli`
+
+[`semantic-release-cli`](https://github.com/semantic-release/cli) allows for easy [installation](installation.md) of **semantic-release** in your Node project as well as setting up the CI configuration:

+# Configuration
+
+In order to customize **semantic-release**’s behavior, [options](#options) and [plugins](plugins.md) can be set via:
+- A `.releaserc` file, written in YAML or JSON, with optional extensions: .`yaml`/`.yml`/`.json`/`.js`
+- A `release.config.js` file that exports an object
+- A `release` key in the project's `package.json` file
+- CLI arguments
+
+The following two examples are the same.
+
+Via CLI argument:
+
+```bash
+$ semantic-release --branch next
+```
+
+Via `release` key in the project's `package.json` file:
+
+```json
+"release": {
+  "branch": "next"
+}
+```
+```bash
+$ semantic-release
+```
+
+**Note**: CLI arguments take precedence over options configured in the configuration file.
+
+**Note**: Plugin options cannot be defined via CLI arguments and must be defined in the configuration file.

+For [Node modules projects](https://docs.npmjs.com/getting-started/creating-node-modules) we recommend installing **semantic-release** locally and running the `semantic-release` command with [npx](https://www.npmjs.com/package/npx):
+
+```bash
+$ npm install --save-dev semantic-release
+```
+
+Then in the CI environment:
+
+```bash
+$ npx semantic-release
+```
+
+**Note:** `npx` is a tool bundled with `npm@>=5.2.0`. It is used to conveniently find the semantic-release binary and to execute it. See [What is npx](../support/FAQ.md#what-is-npx) for more details.
+
+## Global installation
+
+For other type of projects we recommend installing **semantic-release** directly in the CI environment, also with [npx](https://www.npmjs.com/package/npx):
+
+```bash
+$ npx semantic-release
+```
+
+**Note:** For a global installation, it's recommended to specify the major **semantic-release** version to install (for example with with `npx semantic-release@12`, or `npm install -g semantic-release@12`). This way your build will not automatically use the next major **semantic-release** release that could possibly break your build. You will have to upgrade manually when a new major version is released.
+
+**Note:** `npx` is a tool bundled with `npm@>=5.2.0`. It is used to conveniently install the semantic-release binary and to execute it. See [What is npx](../support/FAQ.md#what-is-npx) for more details.

+# Plugins
+
+Each [release step](../../README.md#release-steps) is implemented within a plugin or a list of plugins that can be configured. This allows for support of different [commit message formats](../../README.md#commit-message-format), release note generators and publishing platforms.
+
+See [plugins list](../extending/plugins-list.md).
+
+## Plugin types
+
+### verifyConditions plugin
+
+Responsible for verifying conditions necessary to proceed with the release: configuration is correct, authentication token are valid, etc...
+
+Default implementation: [@semantic-release/npm](https://github.com/semantic-release/npm#verifyconditions) and [@semantic-release/github](https://github.com/semantic-release/github#verifyconditions).
+
+### analyzeCommits plugin
+
+Responsible for determining the type of the next release (`major`, `minor` or `patch`).
+
+Default implementation: [@semantic-release/commit-analyzer](https://github.com/semantic-release/commit-analyzer).
+
+### verifyRelease plugin
+
+Responsible for verifying the parameters (version, type, dist-tag etc...) of the release that is about to be published match certain expectations. For example the [cracks plugin](https://github.com/semantic-release/cracks) is able to verify that if a release contains breaking changes, its type must be `major`.
+
+Default implementation: none.
+
+### generateNotes plugin
+
+Responsible for generating release notes.
+
+Default implementation: [@semantic-release/release-notes-generator](https://github.com/semantic-release/release-notes-generator).
+
+### prepare plugin
+
+Responsible for preparing the release, including:
+- Creating or updating files such as `package.json`, `CHANGELOG.md`, documentation or compiled assets.
+- Create and push commits
+
+Default implementation: [@semantic-release/npm](https://github.com/semantic-release/npm#prepare).
+
+### publish plugin
+
+Responsible for publishing the release.
+
+Default implementation: [@semantic-release/npm](https://github.com/semantic-release/npm#publish) and [@semantic-release/github](https://github.com/semantic-release/github#publish).
+
+### success plugin
+
+Responsible for notifying of a new release.
+
+Default implementation: [@semantic-release/github](https://github.com/semantic-release/github#success).
+
+### fail plugin
+
+Responsible for notifying of a failed release.
+
+Default implementation: [@semantic-release/github](https://github.com/semantic-release/github#fail).
+
+## Configuration
+
+Plugin can be configured by specifying the plugin's module name or file path directly as a `String` or within the `path` key of an `Object`.
+
+Plugins specific options can be set similarly to the other **semantic-release** [options](configuration.md#options) or within the plugin `Object`. Plugins options defined along with the other **semantic-release** [options](configuration.md#options) will apply to all plugins. Options defined within the plugin `Object` will apply to that specific plugin.
+
+For example:
+```json
+{
+  "release": {
+    "verifyConditions": [
+      {
+        "path": "@semantic-release/exec",
+        "cmd": "verify-conditions.sh"
+      },
+      "@semantic-release/npm",
+      "@semantic-release/github"
+    ],
+    "analyzeCommits": "custom-plugin",
+    "verifyRelease": [
+      {
+        "path": "@semantic-release/exec",
+        "cmd": "verify-release.sh"
+      },
+    ],
+    "generateNotes": "./build/my-plugin.js",
+    "githubUrl": "https://my-ghe.com",
+    "githubApiPathPrefix": "/api-prefix"
+  }
+}
+```
+
+With this configuration:
+- the `custom-plugin` npm module will be used to [analyze commits](#analyzecommits-plugin)
+- the `./build/my-plugin.js` script will be used to [generate release notes](#generatenotes-plugin)
+- the [`@semantic-release/exec`](https://github.com/semantic-release/exec),  [`@semantic-release/npm`](https://github.com/semantic-release/npm) and [`@semantic-release/exec`](https://github.com/semantic-release/exec) plugins will be used to [verify conditions](#verifyconditions-plugin)
+- the [`@semantic-release/exec`](https://github.com/semantic-release/exec) plugin will be used to [verify the release](#verifyrelease-plugin)
+- the `cmd` option will be set to `verify-conditions.sh` only for the [`@semantic-release/exec`](https://github.com/semantic-release/exec) plugin used to [verify conditions](#verifyconditions-plugin)
+- the `cmd` option will be set to `verify-release.sh` only for the [`@semantic-release/exec`](https://github.com/semantic-release/exec) plugin used to [verify the release](#verifyrelease-plugin)
+- the `githubUrl` and `githubApiPathPrefix` options will be set to respectively `https://my-ghe.com` and `/api-prefix` for all plugins
