Subject: [PATCH] Modified project to use Mutagen Compose integration.

This commit modifies the docker-compose.yml file to add support for
Mutagen integration. This allows the project to be run on a cloud-based
Docker host while still being edited and accessed locally.

 A simple distributed application running across multiple Docker containers.
 
+**NOTE**: This example has been modified to support integration with
+[Mutagen](https://mutagen.io), allowing the application to be run on a remote
+Docker host while still being edited and accessed locally. For more information,
+please see the
+[relevant documentation](https://mutagen.io/documentation/orchestration/compose).
