By default, this action uses the [Git context](#git-context) so you don't need
to use the [`actions/checkout`](https://github.com/actions/checkout/) action to
check out the repository because this will be done directly by [BuildKit](https://github.com/moby/buildkit).
The git reference will be based on the [event that triggered your workflow](https://docs.github.com/en/actions/reference/events-that-trigger-workflows)
and will result in the following context: `https://github.com/<owner>/<repo>.git#<ref>`.
Building from the current repository automatically uses the [GitHub Token](https://help.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token)

Since [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot)
has [native GitHub Actions support](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem),
to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
