+If you need to run the action on a repository that is not located in [`$GITHUB_WORKSPACE`](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/using-environment-variables#default-environment-variables), you can use the `cwd` option: the action uses a `cd` normal command, so the path should follow bash standards.
