Needed: Steps to install KaosFroyo V30 on HTC Eris

[Norman1080]

Hello all,
This is my first post and my first attempt to install a rom on to my rooted HTC Eris . I have browsed the interwebs quit a bit to find out the steps needed to install a rom. I really don't understand the nandroid process, the busybox process, and the flashing of the rom process. I haven't really come across a step by step process that makes it easy to understand. I don't want to sound naive asking about all of these steps, but I can't find a clear answer. The main reason I ask, is cause I really don't want to brick my phone. If anyone can help simplify the steps it would be greatly appreciated.
