title: Where to put core resources in Symfony2?
body: <p>I started to build a website with Symfony2, and I had a little bit of a quandary about resources.</p>
  
  <p>The Symfony2 Book says that every resource file have to be in a Bundle, but what about the most essential images, .js and .css files that I use in the base.html.twig file on every page?</p>
  
  <p>Should I make a CoreBundle or something similiar, just for these files, or should I put these in the app\Resources folder (or directly in the web folder, maybe)?
  If I can use the app\Resources folder for these, how can I reference these files from the template?</p>
  
  <p>Making a Bundle just for this seems a little unnecesary, and the asset urls for these files are ugly too (e.g. '/bundles/projectcore/images/logo.jpg') in my opinion.</p>
  
  <p>What's the best practice here?</p>
