$ git clone
$ cd heterotic_beast

The last one is optional (it takes a while to execute) but will speed
access to your files, if you are running under Passenger. 

Follow the instructions to create your database and load users.
Configure how you want to deliver the signup emails in config/initializers/mail.rb .
Start the application with
