People who run large-ish research groups/labs: what's your favorite way of doing infrastructure for your lab?

We're planning to do some website updates and such but since I'm basically lab/project managing as part of my postdoc I was also thinking some sort of wiki/knowledge structure.

KidsTeam has a lot of processes and institutional knowledge... it's time to make some sort of manual or something.
