 ## About
 
 GitHub Action to set up Docker [Buildx](https://github.com/docker/buildx).
 
-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.
+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.

+See https://docs.docker.com/build/ci/github-actions/configure-builder/
+
+## Version pinning
+
+This action builds images using [Buildx](https://github.com/docker/buildx) and
+[BuildKit](https://github.com/moby/buildkit). By default, the action will
+attempt to use the latest version of Buildx available on the GitHub Runner
+(the build client) and the latest release of BuildKit (the build server).
+
+To pin to a specific version of Buildx, use the `version` input. For example,
+to pin to Buildx v0.10.0:
 
 ```yaml
-name: ci
+- name: Set up Docker Buildx
+  uses: docker/setup-buildx-action@v3
+  with:
+    version: v0.10.0
+```
 
-on:
-  push:
+To pin to a specific version of BuildKit, use the `image` option in the
+`driver-opts` input. For example, to pin to BuildKit v0.11.0:
 
-jobs:
-  buildx:
-    runs-on: ubuntu-latest
-    steps:
-      -
-        name: Checkout
-        uses: actions/checkout@v2
-      -
-        uses: docker/setup-buildx-action@v1
-        id: buildx
-        with:
-          install: true
-      -
-        name: Build
-        run: |
-          docker build . # will run buildx
+```yaml

-This action is only available for Linux [virtual environments](https://docs.github.com/en/actions/reference/virtual-environments-for-github-hosted-runners#supported-virtual-environments-and-hardware-resources).
+### BuildKit container logs
+
+See https://docs.docker.com/build/ci/github-actions/configure-builder/#buildkit-container-logs
+
+## 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)"
