 ## Usage
 
-### Path context
-
-By default, this action will use the local bake definition (`source: .`), so
-you need to use the [`actions/checkout`](https://github.com/actions/checkout/)
-action to check out the repository.

 ### Git context
 
-Git context can be provided using the [`source` input](#inputs). This means
-that you don't need to use the [`actions/checkout`](https://github.com/actions/checkout/)
+Since `v6` this action uses the [Git context](https://docs.docker.com/build/bake/remote-definition/)
+to build from a remote bake definition by default like the [build-push-action](https://github.com/docker/build-push-action)

 action to check out the repository as [BuildKit](https://docs.docker.com/build/buildkit/)
 will do this directly.
 
+The git reference will be based on the [event that triggered your workflow](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows)
+and will result in the following context: `https://github.com/<owner>/<repo>.git#<ref>`.

 Be careful because **any file mutation in the steps that precede the build step
 will be ignored, including processing of the `.dockerignore` file** since
 the context is based on the Git reference. However, you can use the
