+
+**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

+### 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@v6
+        with:
+          tags: ${{ steps.meta.outputs.tags }}
+          annotations: ${{ steps.meta.outputs.annotations }}
+```
+
+The same can be done with the [`bake-action`](https://github.com/docker/bake-action/):
+
+```yaml
+      -
+        name: Docker meta
+        uses: docker/metadata-action@v5
+        with:
+          images: name/app
+      -
+        name: Build
+        uses: docker/bake-action@v6
+        with:
+          files: |
+            ./docker-bake.hcl
+            cwd://${{ 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
+      -
+        name: Build and push
+        uses: docker/build-push-action@v6
+        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).

-
-#### `tag-sha`
-
-```yaml
-tags: |
-  type=sha
-```
-
-#### `tag-edge` / `tag-edge-branch`
-
-```yaml
-tags: |
-  # default branch
-  type=edge
-  # specify branch
-  type=edge,branch=main
-```
-
-#### `tag-semver`
-
-```yaml
-tags: |
-  type=semver,pattern={{version}}
-```
-
-#### `tag-match` / `tag-match-group`
-
-```yaml
-tags: |
-  type=match,pattern=v(.*),group=1
-```
-
-#### `tag-latest`
-
-`tag-latest` is now handled through the [`flavor` input](README.md#flavor-input):
-
-```yaml
-flavor: |
-  latest=auto
-```
-
-See also the notes about ["latest tag" behavior](README.md#latest-tag)
-
-#### `tag-schedule`
-
-```yaml
-tags: |
-  # default tag (nightly)
-  type=schedule
-  # specific pattern

-
-```yaml
-tags: |
-  type=raw,value=foo
-  type=raw,value=bar
-  # or
-  type=raw,foo
-  type=raw,bar
-  # or
-  foo
-  bar
-```
-
-#### `label-custom`
-
-Same behavior for `labels`:
-
-```yaml
-labels: |
-  maintainer=CrazyMax
-```
