I'm new to litestep and everything.

But I found a theme I really like:

http://customize.org/litestep/themes/1354

And I'm not too good at this kind of stuff to do it by myself. Can someone help me out? I'm really confused reading the ReadMe File.

I was hoping someone could give me a link to a video on how to install themes after you down the litestep program.

After you download a theme. Rename the .zip file to be a .lsz file. Then double click on it.
