title: How to create external wiki on GitLab?
body: <p>I am documenting a dart project. I generated HTML documentation with dartdoc. I don't want this HTML to be put in the project so I read this article: 
  <a href="https://stackoverflow.com/questions/29966292/gitlab-and-html-documentation">Gitlab and HTML documentation</a> about external wiki. </p>
  
  <p>But I can't find this option in my GitLab, so I was wondering if it is still possible or if better solutions exist to implement HTML documentation in GitLab.</p>
  
  <p>Or maybe there are some ways to convert the HTML into markdown to make it easier to put on GitLab.</p>
