Rails automatically creates `app/assets/javascripts/articles.js.coffee`, `app/assets/stylesheets/articles.css.scss`, and `app/helpers/articles_helper.rb` when you generate a new controller.

We aren't going to be using these files and they just add clutter, so let's prevent them from being generated in the first place. (Later we might need the helper file ... we can just create it at that time.)

In `config/application.rb`, add this bit of code toward the bottom:

```ruby
config.generators do |g|
  g.assets false
  g.helper false
end
```
