Michael Schuld will be giving a talk on Git. Git is a version control system, which helps programmers work in teams and fix their screw ups ;)
This meetup will be more programmer centered but can still be useful for other game devs.
Be sure to bring a laptop if you can.
General Topic List:
Unity: best settings for source control
Github: pushing, merging, and pull requests
git: staging, committing, branching, stashing, merging, diffing, gitk
