- Git created by Linus Torvalds, who also created Linux (because Bit-Keeper started asking him money)
- Written in Perl and C
Advantages of DVCS
- Different topologies (centralized, hierarchical, distributed)
- Each clone is a full backup
- Reliable branching/merging
- Full local history (statistics, analyze regressions)
- Deployment
Windows
Mac OSX
- brew install git
- DMG (http://git-scm.com/download/mac)
Linux
- sudo apt-get install git-core (Debian/Ubuntu)
- yum install git-core
