title: How to remove Github's Wiki default sidebar
body: <p>Since a few weeks, Github wikis present a compulsory side bar to the right of wiki pages that take up some space for writing. Example:</p>
  
  <p><img src="https://i.stack.imgur.com/Qud9J.png" alt="enter image description here"></p>
  
  <p>I could not find any button nor instructions on the net to remove this sidebar.</p>
  
  <p>Is there a command or instructions to get it removed somewhere?</p>
