I’ve decided to setup my blog again using Jekyll. I simply followed the instructions from the Jekyll website. The only thing I ended up doing was installing pygments

Installing pyments

sudo pip install pygments

Successfully installed pygments-2.0.2

I then generated a default.css file for the pygments syntax highlighting

pygmentize -S default -f html > css/pygments/default.css

and added it to my template _includes/head.html

The content looks like this
