Some issues:<p>You anchors do not work.<p>For example, for Ruby you have this at the link destination:<p><pre><code> <a name="user-content-ruby"
class="anchor"
href="#ruby"
aria-hidden="true">
<span class="octicon octicon-link"></span></a>
</code></pre>
But it needs to have id='ruby' or name='ruby'<p>Or change the top link to refer to #user-content-ruby and not #ruby.<p>Second, your link to Webby (A Ruby tool) fails. That project moved to github a while ago: <a href="https://github.com/TwP/webby" rel="nofollow">https://github.com/TwP/webby</a><p>But even that is a bit old, because the project is no longer maintained.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.)<p>I think you need to review your links and possible provide some notes to indicate if a project is active.
