title: Can't find application.css.scss in my Rails app
body: <p>I am installing the bootstrap-sass gem and I need to import Bootstrap into application.css.scss like:</p>
  
  <pre><code>@import "bootstrap";
  </code></pre>
  
  <p>however I can't find it in my assets/stylesheets folder. Do I just create it? Will my Rails app load this file?</p>
  
  <p>I do have installed sass-rails:</p>
  
  <pre><code>gem 'sass-rails', '~&gt; 4.0.0'
  </code></pre>
  
  <p>I placed this in my styles.css.scss:</p>
  
  <pre><code>@import 'bootstrap';
  @import 'bootstrap/responsive';
  </code></pre>
  
  <p>Gemfile:</p>
  
  <pre><code>group :assets do
    gem 'bootstrap-sass', '~&gt; 2.3.2.0'
  end
  </code></pre>
  
  <p>Any help is greatly appreciated.</p>
