 ## 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

-### Install by default
+## Configuring your builder
+
+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
-
-on:
-  push:
-
-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
+- name: Set up Docker Buildx
+  uses: docker/setup-buildx-action@v2
+  with:
+    version: v0.10.0
 ```
 
-### BuildKit daemon configuration
-
-You can provide a [BuildKit configuration](https://github.com/moby/buildkit/blob/master/docs/buildkitd.toml.md)
-to your builder if you're using the [`docker-container` driver](https://github.com/docker/buildx/blob/master/docs/reference/buildx_create.md#driver)
-(default) with the `config` or `config-inline` inputs:
-
-#### Registry mirror
-
-You can configure a registry mirror using an inline block directly in your
-workflow with the `config-inline` input:
+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:
 
 ```yaml
-name: ci
-
-on:
-  push:
-
-jobs:
-  buildx:
-    runs-on: ubuntu-latest
-    steps:
-      -
-        name: Set up Docker Buildx
-        uses: docker/setup-buildx-action@v1
-        with:
-          config-inline: |
-            [registry."docker.io"]
-              mirrors = ["mirror.gcr.io"]
-```
-
-#### Max parallelism
-
-You can limit the parallelism of the BuildKit solver which is particularly
-useful for low-powered machines.
-
-You can use the `config-inline` input like the
-previous example, or you can use a dedicated BuildKit config file from your
-repo if you want with the `config` input:
-
-```toml
-# .github/buildkitd.toml
-[worker.oci]
-  max-parallelism = 4
-```
-
-```yaml
-name: ci
-
-on:
-  push:
-
-jobs:
-  buildx:
-    runs-on: ubuntu-latest
-    steps:
-      -
-        name: Set up Docker Buildx
-        uses: docker/setup-buildx-action@v1
-        with:
-          config: .github/buildkitd.toml
-```
-
-### Standalone mode
-
-If you don't have the Docker CLI installed on the GitHub Runner, buildx binary
-is invoked directly, instead of calling it as a docker plugin. This can be
-useful if you want to use the `kubernetes` driver in your self-hosted runner:
-
-```yaml
-name: ci
-
-on:
-  push:
-
-jobs:
-  buildx:
-    runs-on: ubuntu-latest
-    steps:
-      -
-        name: Set up Docker Buildx
-        uses: docker/setup-buildx-action@v1
-        with:
-          driver: kubernetes
-      -
-        name: Build
-        run: |
-          buildx build .
+- name: Set up Docker Buildx
+  uses: docker/setup-buildx-action@v2
+  with:
+    driver-opts: image=moby/buildkit:v0.11.0
 ```

 ### BuildKit container logs
 
-To display BuildKit container logs (when `docker-container` driver is used) you have to [enable step debug logging](https://docs.github.com/en/actions/managing-workflow-runs/enabling-debug-logging#enabling-step-debug-logging)
-or you can also enable debugging in the [setup-buildx action step](https://github.com/docker/setup-buildx-action):
+See https://docs.docker.com/build/ci/github-actions/configure-builder/#buildkit-container-logs
 
-```yaml
-  -
-    name: Set up Docker Buildx
-    uses: docker/setup-buildx-action@v1
-    with:
-      buildkitd-flags: --debug
-```
+## Contributing
 
-Logs will be available at the end of a job:

-## Keep up-to-date with GitHub Dependabot
-
-Since [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot)
-has [native GitHub Actions support](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem),
-to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
-
-```yaml
-version: 2
-updates:
-  # Maintain dependencies for GitHub Actions
-  - package-ecosystem: "github-actions"
-    directory: "/"
-    schedule:
-      interval: "daily"
-```
