 Run Redis and Server
 ----------
 
+If you are running locally then run local redis server
+
 ```bash
 $ redis-server
 ```
 
+On heroku, you can set up `Heroku Redis` add-on and it sets `REDIS_URL` enviornment variable.
+
 In a separate window:
 ```bash
 $ node server
 ```
 
 Note: For production run `export NODE_ENV="production"` before starting the server.
