-
-First, [be a good guy](https://github.com/kossnocorp/etiquette/blob/master/README.md).
-
-## Reporting an issue
-
-Please do a search in [open issues](https://github.com/docker/bake-action/issues?utf8=%E2%9C%93&q=) to see if the issue or feature request has already been filed.
-
-If you find your issue already exists, make relevant comments and add your [reaction](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments). Use a reaction in place of a "+1" comment.
-
-:+1: - upvote
-
-:-1: - downvote
-
-If you cannot find an existing issue that describes your bug or feature, submit an issue using the guidelines below.
-
-## Writing good bug reports and feature requests
-
-File a single issue per problem and feature request.
-
-* Do not enumerate multiple bugs or feature requests in the same issue.
-* Do not add your issue as a comment to an existing issue unless it's for the identical input. Many issues look similar, but have different causes.
-
-The more information you can provide, the more likely someone will be successful reproducing the issue and finding a fix.
-
-You are now ready to [create a new issue](https://github.com/docker/bake-action/issues/new/choose)!
-
-## Closure policy
-
-* Issues that don't have the information requested above (when applicable) will be closed immediately and the poster directed to the support guidelines.
-* Issues that go a week without a response from original poster are subject to closure at our discretion.

 ## 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/)
+action to check out the repository as [BuildKit](https://docs.docker.com/build/buildkit/)
+will do this directly.
+
+```yaml
+name: ci
+
+on:
+  push:
+    branches:
+      - 'master'
+
+jobs:
+  bake:
+    runs-on: ubuntu-latest
+    steps:
+      -
+        name: Set up Docker Buildx
+        uses: docker/setup-buildx-action@v3
+      -
+        name: Login to DockerHub
+        uses: docker/login-action@v3
+        with:
+          username: ${{ secrets.DOCKERHUB_USERNAME }}
+          password: ${{ secrets.DOCKERHUB_TOKEN }}
+      -
+        name: Build and push
+        uses: docker/bake-action@v4
+        with:
+          source: "${{ github.server_url }}/${{ github.repository }}.git#${{ github.ref }}"
+          push: true
+```
+
+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.
+
+Default Git context can also be provided using the [Handlebars template](https://handlebarsjs.com/guide/)
+expression `{{defaultContext}}`. Here we can use it to provide a subdirectory
+to the default Git context:
+
+```yaml
+      -
+        name: Build and push
+        uses: docker/bake-action@v4
+        with:
+          source: "{{defaultContext}}:mysubdir"
+          push: true
+```
+
+Building from the current repository automatically uses the `GITHUB_TOKEN`
+secret that GitHub [automatically creates for workflows](https://docs.github.com/en/actions/security-guides/automatic-token-authentication),
+so you don't need to pass that manually. If you want to authenticate against
+another private repository for remote definitions, you can set the
+[`BUILDX_BAKE_GIT_AUTH_TOKEN` environment variable](https://docs.docker.com/build/building/variables/#buildx_bake_git_auth_token).
+
+> [!NOTE]
+> Supported since Buildx 0.14.0
+
+```yaml
+      -
+        name: Build and push
+        uses: docker/bake-action@v4
+        with:
+          source: "${{ github.server_url }}/${{ github.repository }}.git#${{ github.ref }}"
+          push: true
+        env:
+          BUILDX_BAKE_GIT_AUTH_TOKEN: ${{ secrets.MYTOKEN }}
+```

-to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:

+## Subactions
-    directory: "/"
+
-    schedule:
+### `list-targets`

+
+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.
