title: Github page shows master branch, not gh-pages
body: <p>I've managed to push files to the master branch of my repo as well as a second branch called <code>gh-pages</code>. When I launch <code>mysite.github.io</code> it shows the contents of the master branch. Is there a way to redirect it to <code>gh-pages</code> instead?</p>
  
  <p>I'm doing this from the Mac terminal.</p>
