Git is very easy to install and configure. As I am windows geek I just have to run a wizard to install Git.

As I said I windows geek to I love to work on GUI but I think Git is the only tool where I enjoy will working on command line. On installing Git on windows, it will install Git GUI and Git Bash. Git Bash is its shell or command prompt where you can execute Git commands

You can create public and private repositories, history, version controlling. There’s nothing particularly magical about a repository; it is simply a directory tree in your file system that Git treats as special. You can rename or delete a repository any time you like, using either the command line or your file browser. It uses SSH (Secure Shell) protocol to exchange information in public repositories. All you need to do is to create private and public key and configure it for SSH agent and your information is now on secure channel for Git transactions.

There are a lots of Git command but all are simpler. It mechanism is very simple. If you do not want to go up to advanced level, you can start with just little simple command. Its syntax, keyword and switches are very self explanatory.  Following are 13 simple commands; these are enough to work on basic level. Further branches are introduce that increase complexity
