            - first main difference to SVN
            - advantage of git

            Files can be: 

           ┌─────────┐   ┌──────────┐   ┌────────┐   ┌──────┐   ┌────────┐
           │Untracked│   │Unmodified│   │Modified│   │Staged│   │Commited│
           └─────────┘   └──────────┘   └────────┘   └──────┘   └────────┘

            Git manages these states as:

                       ┌─────────────────┐           ┌─────┐      ┌────┐
                       │Working Directory│           │Index│      │HEAD│
                       └─────────────────┘           └─────┘      └────┘
