Some issues: You anchors do not work. For example, for Ruby you have this at the link destination: <a name="user-content-ruby" class="anchor" href="#ruby" aria-hidden="true"> <span class="octicon octicon-link"></span></a> But it needs to have id='ruby' or name='ruby' Or change the top link to refer to #user-content-ruby and not #ruby. Second, your link to Webby (A Ruby tool) fails. That project moved to github a while ago: https://github.com/TwP/webby https://github.com/TwP/webby But even that is a bit old, because the project is no longer maintained. I believe someone assembled an updated version (to work with recent Ruby changes) but I don't think it's any of the forks of tat project, and I don't recall where I saw it. (I use Webby but hack on my own private copy of the code.) I think you need to review your links and possible provide some notes to indicate if a project is active.
