+### 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:
+
+```yaml
+name: ci
+
+on:
+  push:
+
+jobs:
+  buildx:
+    runs-on: ubuntu-latest
+    steps:
+      -

+            [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:
+      -

+        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:
+      -
