 ## GitHub cache
 
+### Cache backend API
+
+> :test_tube: This cache exporter is considered EXPERIMENTAL until further notice. Please provide feedback on
+> [BuildKit repository](https://github.com/moby/buildkit) if you encounter any issues.
+
+Since [buildx 0.6.0](https://github.com/docker/buildx/releases/tag/v0.6.0) and [BuildKit 0.9.0](https://github.com/moby/buildkit/releases/tag/v0.9.0),
+you can use the [`type=gha` cache exporter](https://github.com/moby/buildkit/tree/master#github-actions-cache-experimental).
+
+GitHub Actions cache exporter backend uses the [GitHub Cache API](https://github.com/tonistiigi/go-actions-cache/blob/master/api.md)
+to fetch and upload cache blobs. That's why this type of cache should be exclusively used in a GitHub Action workflow
+as the `url` (`$ACTIONS_CACHE_URL`) and `token` (`$ACTIONS_RUNTIME_TOKEN`) attributes are populated when a workflow
+is started.
+
+```yaml

+      - 'master'

+### Local cache
+
 > :warning: At the moment caches are copied over the existing cache so it [keeps growing](https://github.com/docker/build-push-action/issues/252).
 > The `Move cache` step is used as a temporary fix (see https://github.com/moby/buildkit/issues/1896).
