title: Clean-up/refactor Github wiki
body: <p>We are using the a GitHub wiki for all our in-company documentation. As this got messy with time we would like to do a clean-up. However we find neither git nor the GitHub front end very convenient to do so.</p>
  
  <p>Are there any tools available to facilitate such a process which I've missed.</p>
  
  <p>Thanks.</p>
