-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—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

+
+## 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.

-
-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`:

-        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

-        with:
-          files: |
-            ./docker-bake.hcl
-            cwd://${{ steps.meta.outputs.bake-file-tags }}
-            cwd://${{ 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

-        with:
-          tags: ${{ steps.meta.outputs.tags }}
-          annotations: ${{ steps.meta.outputs.annotations }}
