+# 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.

+# 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 to 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 guideline](#documentation).
+
+### Give feedback on issues
+
+Some issues are created without information requested in the [Bug report guideline](#bug-report). Help making them easier to resolve by adding any relevant informations.
+
+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 bug 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 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 up 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 request (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 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 i nthe title, in order to get feedback and help from the community.
+- [Allow semantic-release maintainers to make changes to you 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 modification must have:
+- No [linting](#lint) errors
+- A [test](#tests) for every possible cases 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 modification 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, the first 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 keep a consistent state and consist 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) repository 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 is 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 error directly in your editor and automatically fix them on save.
+
+### Tests
+
+Running the integration test require to install [Docker](https://docs.docker.com/engine/installation) on your machine.
+
+All the [semantic-release](https://github.com/semantic-release) repository use [AVA](https://github.com/avajs/ava) for writing and running tests.
+
+Before pushing your code changes make sure all **test 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) repository 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.

-[![NPM](https://nodei.co/npm/semantic-release.png?downloads=true&downloadRank=true&stars=true)](https://nodei.co/npm/semantic-release/)
+**semantic-release** automates the whole package release workflow including: determining the next version number, generating the release notes and publishing the package.
 
-## What is `semantic-release` about?
+This removes the immediate connection between human emotions and version numbers, strictly following the [Semantic Versioning](http://semver.org) specification.
 
-It fully automates your package's releases. It will determine not only which version to release, but also when – all without you wasting [cognitive resources](https://www.youtube.com/watch?v=FKTxC9pl-WM) on it.
+> Trust us, this will change your workflow for the better. – [egghead.io](https://egghead.io/lessons/javascript-how-to-write-a-javascript-library-automating-releases-with-semantic-release)
 
-It is fully integrated into the `npm` lifecycle, so all you need to do is to configure your CI to regularly `npm publish` (i.e. for every commit).
+## Highlights
 
-It removes human decisions and emotions from version numbers and releases – suddenly, strictly following the [SemVer](http://semver.org/) spec isn't a problem anymore.

 ## How does it work?
 
-Meaningful conventions. Instead of dumping [lols](http://whatthecommit.com/) into our commit messages, we can take some time to think about what we changed in the codebase and write it down. Following formalized conventions it this then possible to not only generate a helpful changelog, but to determine whether a new version should be released.
+### Commit message format
 
-This module ships with the [AngularJS Commit Message Conventions](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit), but you can [define your own](https://github.com/boennemann/semantic-release/wiki/commit-analysis).
+**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 publish the release.
 
-### The `prepublish` step
+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.
 
-Before `npm` actually gets to publish a new version `semantic-release`'s `prepublish` step does the following:
+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 contributor and enforce valid commits message.
 
-- Extract all commits since the last version was published
-- Determine the release type (`major`|`minor`|`patch`) or abort if nothing relevant changed
-- Increase the version number accordingly
+Here is an example of the release type that will be done based on a commit messages:
 
-### The `publish` step
+| Commit message                                                                                                                                                                                   | Release type               |
+|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------|
+| `fix(pencil): stop graphite breaking when too much pressure applied`                                                                                                                             | Patch Release              |
+| `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 |
 
-`npm` does its thing.
+### Automation with CI
 
-### The `postpublish` step
+**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).
 
-After `npm` published the new version the `postpublish` step does this:
+### Triggering a release
 
-- Generate release notes
-- Create a new [GitHub Release](https://help.github.com/articles/about-releases/) (including a git tag) with the release notes
+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 is relevant codebase changes since the last release.
 
-Note: The default release notes are a [changelog](https://github.com/ajoslin/conventional-changelog) that is generated from git metadata, using the AngularJS commit conventions. You can [specify your own release note generator](https://github.com/boennemann/semantic-release/wiki/release-note-generation). 
+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.
 
-Note: This is tied to GitHub, feel free to send PRs for other services.
+### Release steps
 
-Note: `semantic-release` works around a limitation in `npm`'s `prepublish` step. Once a version is published it prints a "Could not pack" error that you can *safely ignore* [npm/npm#7118](https://github.com/npm/npm/issues/7118).
+After running the tests the command `semantic-release` will execute the following steps:
 
-## How you can set it up
+| Step              | Description                                                                                                                                                           |
+|-------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| Verify Conditions | Verify all the conditions to proceed with the release with the [verify conditions plugins](docs/usage/plugins.md#verifyconditions-plugin).                            |
+| Get last release  | Obtain last release with the [get last release plugin](docs/usage/plugins.md#getlastrelease-plugin).                                                                  |
+| Analyze commits   | Determine the type of release to do with the [analyze commits plugin](docs/usage/plugins.md#analyzecommits-plugin) based on the commits added since the last release. |
+| Verify release    | Verify the release conformity with the [verify release plugins](docs/usage/plugins.md#verifyrelease-plugin).                                                          |
+| Generate notes    | Generate release notes with the [generate notes plugin](docs/usage/plugins.md#generatenotes-plugin) for the commits added since the last release.                     |
+| Publish           | Publish the release with the [publish plugins](docs/usage/plugins.md#publish-plugin).                                                                                 |

-What this does:
-
-#### Scripts
-
-The setup command configures `scripts` inside the `package.json`:
-
-```json
-"scripts": {
-  "prepublish": "semantic-release pre",
-  "postpublish": "semantic-release post"
-}
-```
-
-Note: If you have already configured `scripts` for `prepublish` or `postpublish` they're just executed one after another. For example: `"npm run babelify && semantic-release pre"`.
-
-#### Version
-
-It would be preferable not to have a version field in the `package.json` at all, but due to an `npm` limitation it is required to have a _not yet published_ version in there [npm/npm#7118](https://github.com/npm/npm/issues/7118). Because of this the version gets changed to `"0.0.0-semantically-released"` until `npm` _hopefully_ removes its limitations.
-
-#### Repository
-
-If you haven't defined your GitHub repository in the `package.json`s [repository field](https://docs.npmjs.com/files/package.json#repository) the remote `origin`'s repository is used. 
-
-### CI Server
-
-Inside your `.travis.yml`:
-
-```yml 
-language: node_js
-node_js:
-- iojs-v1
-sudo: false
-cache:
-  directories:
-  - node_modules
-notifications:
-  email: false
-# See https://github.com/boennemann/semantic-release/issues/18
-before_deploy:
-- npm config set spin false --global
-env:
-  # Get your token here: https://github.com/settings/tokens/new
-  # Grant the token repo/public_repo scope (all others can be deselected)
-  # You should encrypt this:
-  # `travis encrypt GH_TOKEN=<token> --add`
-  global: GH_TOKEN=<github-access-token-with-access-to-your-repo>
-deploy:
-  provider: npm
-  email: <your-npm-mail@example.com>
-  # Very important. Don't forget this one.
-  skip_cleanup: true
-  # Travis currently only supports the old auth key format.
-  # Do `echo -n "<username>:<password>" | base64` to get it.
-  # You should encrypt this:
-  # `travis encrypt $(echo -n "<username>:<password>" | base64) --add deploy.api_key`
-  api_key: <npm-api-key>
-  on:
-    branch: master
-    repo: <user>/<repo>
-```
-
-Note: This isn't tied to a specific service, but example configuration is provided for [Travis CI](https://travis-ci.org/). Feel free to contribute configuration for other servers or services.
-
-Note: You should [encrypt](http://docs.travis-ci.com/user/environment-variables/#sts=Secure Variables) your api keys and tokens.
-
-Note: Your CI environment has to export `CI=true` in order for `semantic-release` not to automatically perform a dry run. Travis CI does this by default. 
-
-Note: It is crucial that your CI server also fetches all tags when checking out your repository. Travis CI does this by default. 
-
-Note: If you have a more sophisticated build with multiple jobs you should have a look at [travis-after-all](https://github.com/dmakhno/travis_after_all), which is also configured for this [package](.travis.yml).
-
-## 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're running `npm publish` locally `semantic-release` automatically performs a dry run. This does log the version that would currently get published, but only if you `git fetch --tags` before.
-
-### Can I run this on my own machine rather than on a CI server?
-
-Of course you can, but this doesn't necessarly 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 GitHub tokens lying around and everything. That said, you can either set the environment variable `CI=true`, or run the scripts with `--debug=false` explicitly. Don't forget to export `GH_TOKEN=your_token` as well.
-
-### Can I manually trigger the release of a specific version?
-
-You can trigger a release by pushing to your repository. You deliberately can not trigger a _specific_ version release, because this is the whole point of `semantic-release`. Start your packages with `1.0.0` and semver on.  
-
-Note: The default commit message conventions do not support pre-release flags, but you can build this in yourself using [custom analyzers](https://github.com/boennemann/semantic-release/wiki/commit-analysis).
-
-### How do I get back to good ol' `npm publish`?
-
-`npm` offers the `--ignore-scripts` flag. Doing `npm publish --ignore-scripts` doesn't execute the `prepublish` and `postpublish` scripts.
-
-### 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, configure your CI server to release only on the `production`/`deploy`/`release` branch and push your code there in certain intervals.
-
-### Why should I trust `semantic-release` with my releases? What if it breaks?
-
-`semantic-release` has a full integration-test suite that tests _actual_ `npm` publishes and _actual_ GitHub Releases (with private registry/API) on node.js `^0.10`, `^0.12` and io.js `^1`. A new version won't get published if it doesn't pass on all these engines.

+# Using semantic-release with [GitLab CI](https://about.gitlab.com/features/gitlab-ci-cd)
+
+## Environment variables
+
+The [Authentication](../usage/ci-configuration.md#authentication) environment variables can be configured with [Secret variables](https://docs.gitlab.com/ce/ci/variables/README.html#secret-variables).
+
+## 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--8).
+
+### `.gitlab-ci.yml` configuration for Node projects
+
+This example is a minimal configuration for **semantic-release** with a build running Node 4, 6 and 8 on Linux. 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
+stages:
+    - test
+    - release
+
+before_script:
+  - npm install
+
+node:4:
+  image: node:4
+  stage: test
+  script:
+    - npm test

+    - npm run semantic-release
+
+    # Only for a global semantic-release installation
+    - npm install -g semantic-release
+    - semantic-release
+```
+
+### `package.json` configuration
+
+A `package.json` is required only for [local](../usage/installation.md#local-installation) **semantic-release** installation.
+
+```json
+{
+  "devDependencies": {
+    "semantic-release": "^12.0.0"

+# Using semantic-release with [Travis CI](https://travis-ci.org)
+
+## Environment variables
+
+The [Authentication](../usage/ci-configuration.md#authentication) environment variables can be configured in [Travis Repository Settings](https://docs.travis-ci.com/user/environment-variables/#defining-variables-in-repository-Settings) or with the [travis env set CLI](https://github.com/travis-ci/travis.rb#env).
+
+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).
+
+## Single Node job configuration
+
+For projects that require to be tested only with a single [Node version](https://docs.travis-ci.com/user/getting-started/#Selecting-a-different-programming-language) on [one Operating System](https://docs.travis-ci.com/user/getting-started/#Selecting-infrastructure-(optional)).
+
+**Note**: [Node 8 is the minimal version required](../support/FAQ.md#why-does-semantic-release-require-node-version--8).
+
+### `.travis.yml` configuration for single Node job
+
+This example is a minimal configuration for semantic-release with a build running Node 8 on Linux. See [Travis - Customizing the Build](https://docs.travis-ci.com/user/customizing-the-build) for additional configuration options.
+
+It's recommended to run the `semantic-release` command in the [Travis `deploy` step](https://docs.travis-ci.com/user/customizing-the-build/#The-Build-Lifecycle) so if an error occurs the build will fail and Travis will send a notification.
+
+**Note**: It's not recommended to run the `semantic-release` command in the Travis `script` step as each script in this step will be executed regardless of the outcome of the previous one. See [travis-ci/travis-ci#1066](https://github.com/travis-ci/travis-ci/issues/1066).
+
+**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
+language: node_js

+  },
+  "scripts": {

+}
+```
+
+## Multiple Node jobs configuration
+
+For projects that require to be tested with multiple [Node versions](https://docs.travis-ci.com/user/languages/javascript-with-nodejs/#Specifying-Node.js-versions) and/or on multiple [Operating Systems](https://docs.travis-ci.com/user/multi-os).
+
+**Note**: At least one job must run a [Node >= 8 version](../support/FAQ.md#why-does-semantic-release-require-node-version--83).
+
+### `.travis.yml` configuration for multiple Node jobs
+
+This example is a minimal configuration for **semantic-release** with a build running Node 4, 6 and 8 on Linux and OSX. See [Travis - Customizing the Build](https://docs.travis-ci.com/user/customizing-the-build) for additional configuration options.
+
+This example uses [`travis-deploy-once`](https://github.com/semantic-release/travis-deploy-once) in order to command [Run `semantic-release` only after all tests succeeded](../usage/ci-configuration.md#run-semantic-release-only-after-all-tests-succeeded).

+# 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 install -g semantic-release && semantic-release
+```
+
+See the [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on specific CI environments.
+
+## 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](../usage/ci-configuration.md) for more details on specific CI environments.
+
+## 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](../usage/ci-configuration.md) 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> npm run 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.

+# 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`](https://github.com/zkat/npx) is a CLI to execute npm binaries. It is bundled with [npm](https://www.npmjs.com/package/npm) >= 5.4, or can be installed via `npm install -g npx`.
+
+`npx` can be used to download the latest [Node 8 package published on npm](https://www.npmjs.com/package/node) and use it to execute the `semantic-release` command.
+
+If you are using a [local](../usage/installation.md#local-installation) **semantic-release** installation:
+
+```bash
+$ npm install -g npx && npx -p node@8 -c "npm run semantic-release"
+```
+
+If you are using a [global](../usage/installation.md#global-installation) **semantic-release** installation:
+
+```bash
+# For global semantic-release install
+$ npm install -g semantic-release npx && npx -p node@8 -c "semantic-release"
+```
+
+### 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.
+
+If you are using a [local](../usage/installation.md#local-installation) **semantic-release** installation:
+
+```bash
+$ nvm install 8 && npm run semantic-release
+```
+
+If you are using a [global](../usage/installation.md#global-installation) **semantic-release** installation:
+
+```bash
+$ nvm install 8 && npm install -g semantic-release && 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>

+# 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).
+
+See [CI configuration recipes](../recipes/README.md#ci-configurations) for more details.
+
+## Authentication
+
+Most **semantic-release** [plugins](plugins.md) require to set up authentication in order to publish to your package manager's registry or to access your project's Git hosted service. The authentication token/credentials have to be made available in the CI serice via environment variables.
+
+See each plugin documentation for the environment variable to set up.
+
+The default [npm](https://github.com/semantic-release/npm#environment-variables) and [github](https://github.com/semantic-release/github#environment-variables) plugins require the following environment variables:

+# Installation
+
+## Local installation
+
+For [Node modules projects](https://docs.npmjs.com/getting-started/creating-node-modules) we recommend to install **semantic-release** locally and to run the `semantic-release` command with a [npm script](https://docs.npmjs.com/misc/scripts):
+
+```bash
+$ npm install --save-dev semantic-release
+```
+
+In your `package.json`:
+
+```json
+"scripts": {
+  "semantic-release": "semantic-release"
+}
+```
+
+Then in the CI environment:
+
+```bash
+$ npm run semantic-release
+```
+
+## Global installation
+
+For other type of projects we recommend to install **semantic-release** globally directly in the CI environment:
+
+```bash
+$ npm install -g semantic-release
+$ semantic-release
+```
+**Note:**: For a global installation, it's recommended to specify the major **semantic-release** version to install (for example with with `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.

+
+Plugin responsible for determining the version of the package last release.
+
+Default implementation: [@semantic-release/npm](https://github.com/semantic-release/npm#getlastrelease).
+
+### analyzeCommits plugin
+
+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
+
+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) allows to verify that if a release contains breaking changes, its type must be `major`.
+
+Default implementation: none.
+
+### generateNotes plugin
+
+Plugin responsible for generating release notes.
+
+Default implementation: [@semantic-release/release-notes-generator](https://github.com/semantic-release/release-notes-generator).
+
+### publish plugin
+
+Plugin responsible for publishing the release.
+
+Default implementation: [npm](https://github.com/semantic-release/npm#publish) and [github](https://github.com/semantic-release/github#publish).
+
+## 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 the other **semantic-release** [options](configuration.md#options) will apply to all plugins, while the one defined within the plugin `Object` will apply only to this 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

+# Shareable configurations
+
+A sharable configuration is an [npm](https://www.npmjs.com/) package that exports a **semantic-release** configuration object. It allows to easily use the same configuration across several projects.
+
+The shareable configurations to use can be set with the [extends](configuration.md#extends) option.
