GIT Tutorial: Installation
How to install GIT on Linux, Windows or Mac
On Linux you can compile the system from source or use commands like the following ones:
yum install git-core
It depends on your distribution.
On Windows the installation is even simpler. You should download the exe file, run it and follow the on-screen instructions. Then you will run GIT through the Windows command line.
The easiest way to install GIT on Mac OS is to use the MacPorts software ( http://www.macports.org) and to run the following command:
sudo port install git-core
