I'm interested in using this gem but am not 100% set, as I'm not sure what it will do. When you run rails g scaffold model_name you get something like this:

Running via Spring preloader in process 12961

      create      app/assets/stylesheets/model_names.scss
      invoke  scss
   identical    app/assets/stylesheets/scaffolds.scss

Can we get something similar for this project in the Readme?
