docker-compose: add aliases to README (#7226)

plugins/docker-compose/README.md

-# Docker-compose plugin for oh my zsh
+# Docker-compose
 
-A copy of the completion script from the [docker-compose](https://github.com/docker/compose/blob/master/contrib/completion/zsh/_docker-compose) git repo.
+This plugin provides completion for [docker-compose](https://docs.docker.com/compose/) as well as some
+aliases for frequent docker-compose commands.
 
+To use it, add docker-compose to the plugins array of your zshrc file:
+```
+plugins=(... docker-compose)
+```
