-# 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

+- 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**.

+
+**Please _DO NOT_ file a public issue**, instead send your report privately to
+[security@docker.com](mailto:security@docker.com).
+
+Security reports are greatly appreciated, and we will publicly thank you for it.
+We also like to send gifts—if you'd like Docker swag, make sure to let
+us know. We currently do not offer a paid security bounty program, but are not

-First, [be a good guy](https://github.com/kossnocorp/etiquette/blob/master/README.md).
-
-## Reporting an issue
-
-Please do a search in [open issues](https://github.com/docker/setup-buildx-action/issues?utf8=%E2%9C%93&q=) to see if the issue or feature request has already been filed.
-
-If you find your issue already exists, make relevant comments and add your [reaction](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments). Use a reaction in place of a "+1" comment.

-:+1: - upvote
-
-:-1: - downvote
-
-If you cannot find an existing issue that describes your bug or feature, submit an issue using the guidelines below.
-
-## Writing good bug reports and feature requests
-
-File a single issue per problem and feature request.
-
-* Do not enumerate multiple bugs or feature requests in the same issue.
-* Do not add your issue as a comment to an existing issue unless it's for the identical input. Many issues look similar, but have different causes.
-
-The more information you can provide, the more likely someone will be successful reproducing the issue and finding a fix.
-
-You are now ready to [create a new issue](https://github.com/docker/setup-buildx-action/issues/new/choose)!
-

 ## 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.
