title: Using Bootstrap with npm and Node.js
body: <p>I'm having a difficult time understanding where/how to use Bootstrap in my nodejs project. I installed Bootstrap with npm, but how do I include it in my index.html file?</p>
  <p>Do I need to include the stylesheet  tag at the top and the  tags above the  tag at the bottom like usual in my .html files, or can I just start applying Bootstrap classes to my elements once I've required it in my app.js file?</p>
  <p>Also, is there an advantage to using npm to install Bootstrap versus using the CDNs?</p>
