Where is the documentation?

["M. Edward (Ed) Borasky" <znmeb znmeb net>]

I just installed a pre-beta Fedora 18 with GNOME Boxes. I can create a
virtual machine with it, but there is no documentation I can find.
This means

a. I have absolutely no idea where GNOME Boxes is storing virtual disk
images on my machine, and
b. I have no idea how to change the memory size in a GNOME Boxes machine.

Where is the documentation?
