The rails application template and generators are the bulk of the happy_seed
gem.
When you first call happy_seed

You should be able to run these generators at any time. Some require the use of others (for example, sign in with twitter requires devise) and they will generally check to make sure that their dependancies are met.
Documentation for the current generators are:
