newbie Help!

Ok, I made the dvd with fedora 10 on it to install on my G4 powermac  
MDD...I then started the computer with option key held down, chose my  
newly created dvd as my startup source... I was good till I got to the  
partitions setup screen and I'm stumped... where to go from there?  
this stuff looks complicated, but I know if given simple instruction,  
I might be able to get a grasp on it.

Is there a real simple walk-thru somewhere on the net? Thanks, Jeff
