 ## Overview
 
-Compose is a tool that allows you to orchestrate multiple Docker containers.
-With Compose, you can build clusters of containers which provide the resources
-(services, volumes, etc.) needed to build and run a complete distributed
-application.

-You can use Compose to build your app with containers hosted locally, or on a
-remote server, including cloud-based instances - anywhere a Docker daemon can
-run. Its primary use case is for development environments, but it can be used
-just as easily for staging or CI.
