title: How to use Subversion with HelpNDoc
body: <p>I am writing a documentation for a project that involves multiple developers. We use Subversion (SVN) to work on our code base. </p>
  
  <p>I wrote the first draft of the documentation document using <a href="http://www.helpndoc.com" rel="nofollow">HelpNDoc</a>, which I like for the nice tree-view and easy of use; the problem is that there is a single file, so I don't know how to use SVN to allow other developers to contribute to the documentation and update it.</p>
  
  <p>Do you know if it's possible? If not, can you advice a nice software, easy to use, with a tree-view of the documentation that can be used with SVN or makes it possible for multiple users to update it? We use Windows.</p>
