+## Upgrade from v1
+
+`v2` of this action includes significant updates and now uses Docker [Buildx](https://github.com/docker/buildx). It
+works with 3 new optional actions ([login](https://github.com/docker/login-action), [setup-buildx](https://github.com/docker/setup-buildx-action)
+and [setup-qemu](https://github.com/docker/setup-qemu-action)) that we have created. It's also rewritten as a
+[typescript-action](https://github.com/actions/typescript-action/) to be as closed as possible of the
+[GitHub Runner](https://github.com/actions/virtual-environments) during its execution (#71 #92).
+
+[Upgrade notes](UPGRADE.md) and many [usage examples](#usage) have been added to handle most use cases but `v1` is
+still available through [`releases/v1` branch](https://github.com/docker/build-push-action/tree/releases/v1).
