title: How do you merge two git branches that are in different local repos/folders?
body: <p>I have:</p>
  
  <pre><code>folder_a/app_1.0
  folder_b/app_1.1
  </code></pre>
  
  <p>And let's just say I'm working off of the master branch in both folders/repos. </p>
  
  <p>How can I merge the branches together?</p>
