+You will need to add an initializer to configure Paperclip.  If on Rails, can add a config/initializers/paperclip.rb, on Merb
+can use config/init.rb and add it to the Merb::BootLoader.after_app_loads section.  Can also use environment configs, rackup
+file, Rake task, wherever.

 Your database will need to add four columns, avatar_file_name (varchar), avatar_content_type (varchar), and
 avatar_file_size (integer), and avatar_updated_at (datetime).  You can either add these manually, auto-
