-### Building the Container
+### Build and Push (multi-arch)
+
+Use Docker Buildx to build and push a multi-architecture image for both `linux/amd64` and `linux/arm64` in a single command. Replace `trycua` with your Docker Hub username or your registry namespace as needed.
 
 ```bash
-docker build -t cua-ubuntu:latest .
