-## 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 >= 10.18](#why-does-semantic-release-require-node-version--1018) 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 >= 10.18.
-
-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`.

+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:
