If you add a link like this https://htmlpreview.github.io/?https://github.com/adam-cyclones/didi/blob/master/docs/generated/index.html<< (dead link now)

The link passes through a proxy which renders html pages. https://github.com/htmlpreview/htmlpreview.github.com

Basically it's a great way to view html index's in your repo without needing to setup pages.
