Default [q] atom rom cfw

I was reading on a French website about Atom Rom and how it was the best rom for the Razr I, however, I'm not sure whether it would brick my phone, or something! I only ever trust downloads from XDA and I was wondering if anyone could give me the download link for Atom Rom for the XT890 and a simple tutorial on how to install it? It worried me that you had to use your PC to install it? Normally I just flash if via CWM!
Okay thanks
