+**NOTE**: Not sure where this would go in an accepted PR.
+
+Building a multiple-architecture image requires using the Docker `buildx` plugin:
+
+```shell
+docker buildx create --name builder-fast-data-dev
+docker buildx build --platform linux/amd64,linux/arm64 \
+   --tag your-docker-repo/fast-data-dev:latest \
+   --pull --push --builder builder-fast-data-dev .
