title: Git Tower add existing files as a branch
body: <p>I'm working on a WordPress plugin that I started developing before I started using Git. At one point, I created a copy of the plugin in a different folder to experiment with an alternate way of writing one part of the plugin. I recently purchased Tower and started using Git to track changes for my plugins. I've created a local repo using the first version of this plugin. However, I'd like to add in that second version I created earlier as a branch of the main plugin.</p>
  
  <p>Using Tower as the OS X Git client, how does one add existing files from a different folder as a branch to an existing repo?</p>
  
  <p>I've already tried Refs > Add New Local Branch, but it doesn't add the second version's files, nor does it have a way to point to those files. If I drag the second version's folder from Finder to the Tower icon, it creates a whole new repo. Would I need to do that and somehow merge that in as a branch? </p>
  
  <p>I'm fairly new to Git as a whole and I'm sure there's probably a way to do this easily through CLI, but I'd love to make this work through Tower.</p>
