Who knows me certainly know I am not the biggest…err…fan of Git 
Thanks to Gian Maria and its continuous support on it I managed to understand how Git works and why it is so powerful. I am not saying it is “better than” something else – it is different and it has some pros and some cons.
So, it’s distributed. Distributed does not mean anarchist – it means distributed. If you want to have some sort of centralisation, go for a Remote. You can use it as a shared repository to be used like a central depot without losing any advantage of the DVCS concept.
When you commit something is different than when you push something. A commit is local, a push is toward a Remote.
A Git Fetch gets all the objects from the Remote which are not in your local repository. A Git Pull does more: it merges those files on your local repository, like a Get Latest Version.
Eventually – install SourceTree. It’s an amazing GUI tool with a fantastic branch visualisation tool.
