title: Ruby on Rails asset organisation folders
body: <p>I'm using ruby on rails 5. What is the difference app/assets, lib/assets and vendor/asset? </p>
  
  <p>If I write my own js scripts should they be included in the app/assets? How about if I use a bootstrap library where should I put it at?</p>
  
  <p>And regardless which folder they are in, i am able to access them using <code>javascript_include_tag</code>? Example:</p>
  
  <pre><code>javascript_include_tag "xmlhr"
  </code></pre>
