 ### 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)
+does. This means that you don't need to use the [`actions/checkout`](https://github.com/actions/checkout/)
 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
-[Path context](#path-context) alongside the [`actions/checkout`](https://github.com/actions/checkout/)
-action to remove this restriction.

+## Summaries
+
+This action generates a [job summary](https://github.blog/2022-05-09-supercharging-github-actions-with-job-summaries/)
+that provides a detailed overview of the build execution. The summary shows an
+overview of all the steps executed during the build, including the build
+inputs, bake definition, and eventual errors.
+
+![build-push-action job summary](./.github/bake-summary.png)
+
+The summary also includes a link for downloading a build record archive with
+additional details about the build execution for all the bake targets,
+including build stats, logs, outputs, and more. The build record can be
+imported to Docker Desktop for inspecting the build in greater detail.
+
+Summaries are enabled by default, but can be disabled with the
+`DOCKER_BUILD_SUMMARY` [environment variable](#environment-variables).
+
+For more information about summaries, refer to the
+[documentation](https://docs.docker.com/go/build-summary/).

+## About
+
+This subaction generates a list of Bake targets that can be used in a [GitHub matrix](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstrategymatrix),
+so you can distribute your builds across multiple runners.
