Just...wow. I'm still learning about Git, it's more complete than I ever could imagine but still don't understand but only until I work with someone, the Git is to work with colleagues in a project and still I have the theorical background, I have some questions that can only be answered IRL. The command gitk is very useful to make more...graphic the thing but is better to work from the terminal...I guess. Today I learned how to pull into Github a branch and understood the importance of branches. Good lord, this is fun.

Good practice is always make git pull origin master
