 ## Submitting a pull request
 
 1. [Fork](https://github.com/docker/setup-buildx-action/fork) and clone the repository
 2. Configure and install the dependencies: `yarn install`
 3. Create a new branch: `git checkout -b my-branch-name`
-4. Make your change, add tests, and make sure the tests still pass
-5. Run pre-checkin: `yarn run pre-checkin`
-6. Push to your fork and [submit a pull request](https://github.com/docker/setup-buildx-action/compare)
-7. Pat yourself on the back and wait for your pull request to be reviewed and merged.

-## Container based developer flow
-
-If you don't want to maintain a Node developer environment that fits this project you can use containerized commands instead of invoking yarn directly.
-
-```
-# 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
+5. Make sure the tests pass: `docker buildx bake test`
+6. Format code and build javascript artifacts: `docker buildx bake pre-checkin`
+7. Validate all code has correctly formatted and built: `docker buildx bake validate`
+8. Push to your fork and [submit a pull request](https://github.com/docker/setup-buildx-action/compare)
+9. Pat your self on the back and wait for your pull request to be reviewed and merged.
 
 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**.

-> * [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](https://github.com/docker/buildx). By default, the `docker-container` [builder driver](https://github.com/docker/buildx/blob/master/docs/reference/buildx_create.md#driver)
+will be used to be able to build multi-platform images and export cache thanks to the [BuildKit](https://github.com/moby/buildkit)
+container.
