install cm after rooting topic

Hi, i wanted to ask this to leapinlar in this thread: http://forum.xda-developers.com/show....php?t=2062613, but since i can't, i will ask it openly. I've rooted a Nook HD+ 2.2.0 following that guide succesfully. Now I would like to try out cyanogenmod, but just try it out so if possible i would to run a hybrid configuration without changing to much in the internal file structure. My goal is to be able to use the tablet without the high temps i get whenever i look at videos or even use the web browser in the stock os.

So, after following the guide from that thread what would be most simple way to install cyanogenmod? (i mean, without following the other guide which would mean doing a factory reset, getting a 4gb sd card and other stuff)

Thanks
