The last thing I would like to share with readers is a web app I found useful at the very beginning, to better understand the way Git works.

LearnGitBranching (http://pcottle.github.io/learnGitBranching/) is a tremendously helpful web app that offers you some exercises to help you grow your Git culture. Starting from basic commit exercises, you learn how to branch, rebase, and so on. However, the really cool thing is that at the right side of the page, you will see a funny repository graph evolving in real time, following the commands you type in the emulated shell.
