-issue, please bring it to their attention right away!
-
-**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

+
+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)!
+
+## Closure policy
+
+* Issues that don't have the information requested above (when applicable) will be closed immediately and the poster directed to the support guidelines.
+* Issues that go a week without a response from original poster are subject to closure at our discretion.

 ## Configuring your builder
 
-* [Version pinning](https://docs.docker.com/build/ci/github-actions/configure-builder/#version-pinning): Pin to a specific Buildx or BuildKit version
+See https://docs.docker.com/build/ci/github-actions/configure-builder/
-* [BuildKit container logs](https://docs.docker.com/build/ci/github-actions/configure-builder/#buildkit-container-logs): Enable BuildKit container logs for debugging purposes
+
-* [BuildKit Daemon configuration](https://docs.docker.com/build/ci/github-actions/configure-builder/#buildkit-daemon-configuration)
+## Version pinning
-  * [Registry mirror](https://docs.docker.com/build/ci/github-actions/configure-builder/#registry-mirror): Configure a registry mirror for your builds
+
-  * [Max parallelism](https://docs.docker.com/build/ci/github-actions/configure-builder/#max-parallelism): Configure the maximum parallelism for your builds
+This action builds images using [Buildx](https://github.com/docker/buildx) and
-* [Append additional nodes to the builder](https://docs.docker.com/build/ci/github-actions/configure-builder/#append-additional-nodes-to-the-builder): Create additional nodes for your builder
+[BuildKit](https://github.com/moby/buildkit). By default, the action will
-* [Authentication for remote builders](https://docs.docker.com/build/ci/github-actions/configure-builder/#authentication-for-remote-builders)
+attempt to use the latest version of Buildx available on the GitHub Runner
-  * [SSH authentication](https://docs.docker.com/build/ci/github-actions/configure-builder/#ssh-authentication): Authenticate to a remote builder using SSH
+(the build client) and the latest release of BuildKit (the build server).
-  * [TLS authentication](https://docs.docker.com/build/ci/github-actions/configure-builder/#tls-authentication): Authenticate to a remote builder using TLS
+
-* [Standalone mode](https://docs.docker.com/build/ci/github-actions/configure-builder/#standalone-mode): Use Buildx as a standalone binary (without the Docker CLI)
+To pin to a specific version of Buildx, use the `version` input. For example,
-* [Isolated builders](https://docs.docker.com/build/ci/github-actions/configure-builder/#isolated-builders): Create isolated builders for your builds
+to pin to Buildx v0.10.0:
+
+```yaml
+- name: Set up Docker Buildx
+  uses: docker/setup-buildx-action@v3
+  with:
+    version: v0.10.0
+```
+
+To pin to a specific version of BuildKit, use the `image` option in the

+## Using on GHES
+
+GitHub Runners come [pre-installed with Docker Buildx](https://github.com/actions/runner-images/blob/main/images/linux/Ubuntu2204-Readme.md)
+following your virtual environment. If you specify a version or `latest` of
+Docker Buildx in your workflow, the version will be downloaded from [GitHub Releases in `docker/buildx`](https://github.com/docker/buildx/releases)
+repository. These calls to `docker/buildx` are made via unauthenticated requests,
+which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting).
+
+If more requests are made within the time frame, then you will start to see
+rate-limit errors during downloading that looks like:
+
+```
+##[error]API rate limit exceeded for...
+```
+
+To get a higher rate limit, you can [generate a personal access token on github.com](https://github.com/settings/tokens/new)
+and pass it as the `github_token` input for the action:
+
+```yaml
+uses: docker/setup-buildx-action@v3
+with:
+  github_token: ${{ secrets.GH_DOTCOM_TOKEN }}
+  version: v0.10.1
+```
+
+If the runner is not able to access `github.com`, it will take the default one
+available on the GitHub Runner or runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)"
