+# Reporting security issues
+
+The project maintainers take security seriously. If you discover a security
+issue, please bring it to their attention right away!
+
+**Please _DO NOT_ file a public issue**, instead send your report privately to
+[security@docker.com](mailto:security@docker.com).
+
+Security reports are greatly appreciated, and we will publicly thank you for it.
+We also like to send gifts&mdash;if you'd like Docker swag, make sure to let
+us know. We currently do not offer a paid security bounty program, but are not
+ruling it out in the future.

-## Reporting an issue
-
-Please do a search in [open issues](https://github.com/docker/metadata-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/metadata-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.

+### Annotations
+
+Since Buildx 0.12, it is possible to set annotations to your image through the
+`--annotation` flag.
+
+With the [`build-push-action`](https://github.com/docker/build-push-action/),
+you can set the `annotations` input with the value of the `annotations` output
+of the `metadata-action`:
+
+```yaml
+      -
+        name: Docker meta
+        uses: docker/metadata-action@v5
+        with:
+          images: name/app
+      -
+        name: Build and push
+        uses: docker/build-push-action@v5
+        with:
+          tags: ${{ steps.meta.outputs.tags }}
+          annotations: ${{ steps.meta.outputs.annotations }}
+```
+
+The same can be done with the [`bake-action`](https://github.com/docker/bake-action/):
+
+```yaml
+      -
+        name: Docker meta
+        uses: docker/metadata-action@v5
+        with:
+          images: name/app
+      -
+        name: Build
+        uses: docker/bake-action@v3
+        with:
+          files: |
+            ./docker-bake.hcl
+            ${{ steps.meta.outputs.bake-file-tags }}
+            ${{ steps.meta.outputs.bake-file-annotations }}
+          targets: build
+```
+
+Note that annotations can be attached at many different levels within a manifest.
+By default, the generated annotations will be attached to image manifests,
+but different registries may expect annotations at different places;
+a common practice is to read annotations at _image indexes_ if present,
+which are often used by multi-arch builds to index platform-specific images.
+If you want to specify level(s) for your annotations, you can use the
+[`DOCKER_METADATA_ANNOTATIONS_LEVELS` environment variable](#environment-variables)
+with a comma separated list of all levels the annotations should be attached to (defaults to `manifest`).
+The following configuration demonstrates the ability to attach annotations to both image manifests and image indexes,
+though your registry may only need annotations at the index level. (That is, `index` alone may be enough.)
+Please consult the documentation of your registry.
+
+```yaml
+      -
+        name: Docker meta
+        uses: docker/metadata-action@v5
+        with:
+          images: name/app
+        env:
+          DOCKER_METADATA_ANNOTATIONS_LEVELS: manifest,index
+      -
+        name: Build and push
+        uses: docker/build-push-action@v5
+        with:
+          tags: ${{ steps.meta.outputs.tags }}
+          annotations: ${{ steps.meta.outputs.annotations }}
+```
+
+More information about annotations in the [BuildKit documentation](https://github.com/moby/buildkit/blob/master/docs/annotations.md).
