+### Overwrite labels
+
+If some of the [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)
+labels generated are not suitable, you can overwrite them like this:
+
+```yaml
+      -
+        name: Build and push
+        uses: docker/build-push-action@v2
+        with:
+          context: .
+          file: ./Dockerfile
+          platforms: linux/amd64,linux/arm64,linux/386
+          push: ${{ github.event_name != 'pull_request' }}
+          tags: ${{ steps.docker_meta.outputs.tags }}
+          labels: |
+            ${{ steps.docker_meta.outputs.labels }}
+            org.opencontainers.image.title=MyCustomTitle
+            org.opencontainers.image.description=Another description
