Using GIT
Using GIT for version control system is really very easy. The best guide I found of how t use Git is website Git for the lazy. I was surprise how easy to use GIT is. If you need another place to check for how to use GIT you can try Everyday GIT with 20 commands or So.
The use of GIT become even easier with tools like GitX. It is a Max OS X application which provided the possibility to see the the changes history and also commit the current changes to GIT. How it worked? Basically after making the changes in your code go the Commit View of GitX. It will show the new changes you had made. Choose what changes you want to commit into GIT. Include your message, and click in the Commit button. And this is it. You can go to the History Browser to see how your code had been growing.

GitX – History Browser
Another tool which I have not yet tested but looks nice is github. The advertise strength of this one is social coding.
