Twitter on Arjuna

Hi,

start installed my new blog and all, and I’m using the new Arjuna Theme (Arjuna X 1.0.4 by SRS Solutions). I would like to add a simple twitter button (you know, that blue t thing) next to the existing RSS one. I know the link is pretty simple, but I can’t figure out my way in the php file to set it up.. what do I do, where do I do it?

I would also like to add similar buttons in the future for facebook and linkedin.

Thanks!
