title: What's exactly the purpose of Components, Layouts and Pages folders in a Meteor-React project?
body: <p>I'm starting a new project with Meteor and I would like to use the <code>--full</code> architecture when creating the project: <code>meteor create myApp --full</code></p>
  
  <p>However, I don't really understand the purpose and differences of some folders in imports/ui/ :</p>
  
  <ul>
  <li>components</li>
  <li>layouts</li>
  <li>pages</li>
  </ul>
  
  <p>Especially the difference between <code>layouts</code> and <code>pages</code>. What type of code should they contain ?</p>
