+You'll need ruby and redis installed to run this.  If you're on a mac, one way to go getting redis is to install [homebrew](https://brew.sh/), then run `brew install redis`.
+Another way is to install [docker](https://docs.docker.com/docker-for-mac/install/),
+then run `docker run --name redis -p 6379:6379 -d redis`.
+Then, for ruby, install [rvm](https://rvm.io/).
 
 Once ruby + redis are installed you can just run `redis-server` in a terminal to start redis.
