title: 404 error on the default page on my Gitlab repository
body: <p>This is my first time using Gitlab.<br>
  My repository url is <code>myusername.gitlab.io/myrepo</code>.
  Opening that page gives me a 404 error, however when I open  <code>myusername.gitlab.io/myrepo/myindex.html</code>, I get my index page.</p>
  
  <p>Can someone tell me how I can set it so <code>myusername.gitlab.io/myrepo</code> loads <code>myusername.gitlab.io/myrepo/myindex.html</code>.</p>
  
  <p>On a second note, I have seen other projects that use username.gitlab.io<code>without the need for the</code>/therepo` suffix.
  Can anyone tell me how I can remove the suffix and just use the domain to access my repo.</p>
