title: Linking repo subfolders with git
body: <p>I have a project on Red Hat OpenShift (git) and a project on Bitbucket (git).</p>
  
  <p><strong>How do I link a subfolder of the Bitbucket project to a subfolder of the OpenShift project?</strong></p>
  
  <p>(so that making commits in one subfolder makes those same commits in the other)</p>
