Well you should do it right from the beginning:
I wrote 3 new howtos:

http://wiki.nixos.org/wiki/Main_Page#HOWTOs
Titles:

= How to find the package you're looking for in Nix

= How to keep multiple packages up to date at once (example for
pkgs.misc.collection)

= How to find any text in code fast (gnu idutils)

For you the second howto (keep multiple packages up to date)
is important.

Maybe I duplicated information. But I think its important that we can
help people fast.
