title: How to generate .keystore file using Google App Signing certificate?
body: <p>What I have done</p>
  
  <ol>
  <li>I've created app, signed it as described <a href="https://facebook.github.io/react-native/docs/signed-apk-android.html" rel="nofollow noreferrer">here</a></li>
  <li>I've uploaded the generated bundle to Google Play and got access to the page with App signing certificate and Upload certificate</li>
  </ol>
  
  <p>Now what? How do i create new .keystore file using App signing certificate or Upload certificate? Also, which one should i use?</p>
  
  <p>I'm on OS X, if this is important.</p>
