title: Why does gerrit ls-groups command on my project show no default groups
body: <p>Following the link below, I tried to run ls-groups on my new gerrithub project I set up. I have already put my public ssh key into the my profile settings so I can successfully connect to it. I am the creator of the project, but when I run ls-groups on the project, it connects and runs but returns nothing. I thought each gerrit project had a list of default groups like administrator, etc.?</p>

  <p>Here is the command example I was using:</p>
  
  <pre><code>ssh -p 29418 username@review.gerrithub.io gerrit ls-groups --project username/projectname
  </code></pre>
