I decided to fork Meatspace (see previous post) because I wanted to host a private chatroom that I could use with friends.
As usual, it was not as straightforward as just download and use.
I ran into a few hurdles. What follows are the steps I took to get it working on Heroku. Heroku allows you to host your apps for free, so feel free to use this as a guide for setting up your own chatroom.
