Sidebad to navigate the document

Hi,

I am looking to add a sidebar, similar to this Customisation page page http://t3-framework.org/documentation/customization.html

I am new to Joomla and dont have CSS or JavaScript knowledge.

Can some one please guide me on adding this option?

I have access to my file through FTP and I am getting a hang of the Joomla 3.3 back-end.

If I am given a step-by-step on adding the sidebar feature than I am sure I can implement it. The explanations I have seen so far in the documentation are too technical. Can someone please simplify?

Thanks,
Tarun
