Default [Q] ClockWork Mod

Hey, I want to install the AOKP ROM that I found here, but I need CWM 6.0.4 in order to flash it, but I already have a version of CWM in my Tablet. How do I update my CWM? Do I just install it as if i didn't have any CWM? Or is there something else I should do? Bascially, what am I supposed to do in order to update CWM? Thanks!
