how do I edit my XF86Config file while in runlevel 3?

[Elton Woo <elwoo videotron ca>]

I'm about to install the nVidia drivers on my system. However, I must
confess that I'm more of a GUI user than a "command-line guru". The 
installation instructions require that I re-edit my /etc/X11/XF86 Config
file *before* booting into X. Could someone guide me on what/how to
do this? (Dummy-level instructions, please!)

I think my previous failures in installing the dirvers are related to my
editing the file *after* booting into the GUI desktop.

TIA

Elton ;-)
