If a quickstart is what you want, below is enough of an
/etc/samba/smb.conf to get you sharing your home directories, as well as
(for example's sake) a directory called /vol. You'll probably want to do
more tweaking, and maybe add printers, but to get *something* working,
just put this file in place and run "smbd -D; nmbd -D" as root (and put
those commands in rc.local)
