Rails 3 compatible generators for gems that don't have them yet
gem install rails3-generators
and add the following to your project's Gemfile
The Factory Girl generators have moved to the factory_girl_rails gem.
The Haml generators have moved to the haml-rails gem.
The jQuery generators have moved to the jquery-rails gem.
The MongoMapper generators moved to the mongo_mapper gem.
The SimpleForm generators moved to the simple_form gem.
The Formtastic generators moved to the fortastic gem.
The Authlogic generators moved to the authlogic gem.
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
