GitHub actually shows a README file for each directory (if one exists), so the recommendation was to change &#x2F;src&#x2F;plugins&#x2F;x&#x2F;documentation.md to &#x2F;src&#x2F;plugins&#x2F;x&#x2F;README.md so that you could see the documentation on this page: <a href="https:&#x2F;&#x2F;github.com&#x2F;umbrellajs&#x2F;umbrella&#x2F;tree&#x2F;master&#x2F;src&#x2F;plugins&#x2F;after" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;umbrellajs&#x2F;umbrella&#x2F;tree&#x2F;master&#x2F;src&#x2F;plugi...</a>
