-```
-# format code and build javascript artifacts
-docker buildx bake pre-checkin
-
-# validate all code has correctly formatted and built
-docker buildx bake validate
-
-# run tests
-docker buildx bake test
-```
+4. Make your changes

 Here are a few things you can do that will increase the likelihood of your pull request being accepted:
 
+- Write tests.
 - Make sure the `README.md` and any other relevant **documentation are kept up-to-date**.
 - We try to follow [SemVer v2.0.0](https://semver.org/). Randomly breaking public APIs is not an option.
 - Keep your change as focused as possible. If there are multiple changes you would like to make that are not dependent upon each other, consider submitting them as **separate pull requests**.

 ## About
 
 GitHub Action to set up Docker [Buildx](https://github.com/docker/buildx).
 
-> :bulb: See also:
-> * [login](https://github.com/docker/login-action) action
-> * [setup-qemu](https://github.com/docker/setup-qemu-action) action
-> * [build-push](https://github.com/docker/build-push-action) action
+This action will create and boot a builder that can be used in the following
+steps of your workflow if you're using Buildx or the [`build-push` action](https://github.com/docker/build-push-action/).
+By default, the [`docker-container` driver](https://docs.docker.com/build/building/drivers/docker-container/)
+will be used to be able to build multi-platform images and export cache using
+a [BuildKit](https://github.com/moby/buildkit) container.
