title: How to manage more than one git repository in VS Code
body: <p>I have to work with a directory like this:</p>
  <pre><code>ProjectRoot
  |---- SubDirectory1
  |---- SubDirectory2(Git Repository1)
  |---- SubDirectory3(Git Repository2)
  |---- ...
  |---- Files
  </code></pre>
  <p>But I found that the embedded git function of VS-code does not automatically recognize those sub-directories managed by git.</p>
  <p>How to solve this problem? Is there a extension about it?</p>
