-From that moment on, `yarn` will be available for you to use in your system.
-This is thanks that `yarn` is shipped with NodeJS since Node 16 (along with other common package managers).
-The version shipped is v1 (classic `yarn`).
-Volto makes sure that you are using the correct version of `yarn` at runtime.
-This is because it's pinned in the Volto boilerplate to use the right version.
-So from this moment on, you don't have to worry about the version of `yarn` you are using, it will adapt to the project's needs.

-These instructions will not work if you have used another package manager, such as Homebrew on macOS, to install Yarn.
-You can verify where you installed Yarn and its version.
-Make sure that you are using the yarn version provided by NodeJS by default
+In your generated Volto project from the previous step, you can find the pinned version of Yarn in its {file}`.yarnrc.yml`.

 yarn -v

 If the console includes `homebrew` in the path, and the version of Yarn is not supported, then you must uninstall it.

 ```shell
 brew uninstall yarn
 ```
