+### Multi-platform build example
+
+The following example shows how to use this action to build and push a multi-platform image for `linux/amd64` and `linux/arm64` using [Buildx](https://github.com/docker/buildx):
+
+```yaml
+name: ci
+
+on:
+  push:
+    branches:
+      - 'main'
+
+jobs:
+  docker:
+    runs-on: ubuntu-latest
+    steps:
+      -
+        name: Set up QEMU
+        uses: docker/setup-qemu-action@v4
+      -
+        name: Set up Docker Buildx
+        uses: docker/setup-buildx-action@v4
+      -
+        name: Login to Docker Hub
+        uses: docker/login-action@v3
+        with:
+          username: ${{ secrets.DOCKERHUB_USERNAME }}
+          password: ${{ secrets.DOCKERHUB_TOKEN }}
+      -
+        name: Build and push
+        uses: docker/build-push-action@v6
