How to install Git on window?


You can install git on window platform either through cygwin or by downloading msysGit. I've chosen the later one: msysGit

Win	Cygwin	http://www.cygwin.com/setup.exe
	msysGit	http://code.google.com/p/msysgit/downloads/list

So, go to msysGit and download the window installer or zip file, whatever that suits you.
Extract/install it.
 Once done, add path to git`s bin directory in window Environment PATH variable.
