title: How to properly manipulate a detached Expo app's VCS
body: <p>I'm programming on Expo for Android and I'm totally new to React-Native and Expo and really can't find something about a detached app's VCS on Expo docs, nor another similar question in the forums or SO (I "detached" my app because I needed <a href="https://github.com/RepairShopr/react-native-signature-capture" rel="nofollow noreferrer">React-Native-signature-capture</a>).</p>
  
  <p>Here are some things to have in mind:</p>
  
  <ol>
  <li>We are a team of 2 developers working with the same app. </li>
  <li>Each one manages his own tasks/issues</li>
  <li>I'm the one who used to build the Expo app with my own expo account when the app was "attached".</li>
  </ol>
  
  <p><a href="https://i.stack.imgur.com/l43J3.png" rel="nofollow noreferrer">When I was About to Stage SourceTree showed me this</a></p>
  
  <p>The thing is, when I was about to stage and commmit React-Native code I saw all the <strong>/.expo-source</strong> and <strong>/android</strong> files and all that weights 10MB!... 10mb on a single commit, is that right? Is there something I can do about it? <strong>Do we need those files on VCS?</strong> Sorry for my bad english.</p>
