OCT2 - a modified version of octopress classic theme (distributed under the same license as Octopress, The MIT license ).

I've included modifications made by Alessandro Melandri. For details, see "Octopress Theme Customization". Also included are css formatting for tables and 4 icons from free-hand drawn Sketch icons.

If you want to enable MathJax,

$ cd .themes/oct2/source/_includes/custom/
$ cp head.mathjax.html head.html

Installing

$ git clone https://github.com/bijumon/oct2.git .themes/
$ rake install["oct2"] 

You also need to add nav.html to default asides in _config.yml

default_asides: [asides/nav.html, asides/recent_posts.html ....
