title: What is the correct way to add bootstrap to a symfony app?
body: <p>I'm using symfony framework 3 to develop a web application. I need to add boostrap's functionality to my application. I installed bootstrap using the below command. (I'm using composer.)</p>
  
  <pre><code>composer require twbs/bootstrap
  </code></pre>
  
  <p>It installs bootstrap to the application's vendor folder. More specifically <code>vendor\twbs\bootstrap</code>.</p>
  
  <p>I need to attach bootstrap's <code>css</code> and <code>js</code> files in the application's twig templates (located in <code>app\Resources\views</code>) as assets. </p>
  
  <p>e.g.:</p>
  
  <pre><code>&lt;link href="{{ asset('css/bootstrap.css') }}" rel="stylesheet" /&gt;
  </code></pre>
  
  <p>But assets only work with files located in the web (<code>web\bundles\framework</code>) folder. I can copy those <code>.css</code> and <code>.js</code> files from the vendor folder to web folder manually to make this work but there should be a proper way to do it (i.e.: to add assets). e.g.: A command with <code>bin/console</code>?</p>
  
  <p>Any help is appreciated. </p>
