Use the guide to prepare good looking posts! The theme has a sidebar which uses 3d transitions. To change the contents of the sidebar, look inside _includes folder for
sidebar.html file and edit it.
Since the theme is based on bootstrap, you can use bootstrap classes. Take a look at elements page.
By default the site name is Webjeda Gatok. Change it in
_config.yml file by changing
title: Webjeda Gatok.
I have designed the logo which suits for this site. You either use other logo or keep the original. I do not claim the copyrights :)
