Principles of Operation
Several program functions (init, add, rm …) are accessed by the git command. The .git directory is the datastore.
Files within a directory with .git directory can be either tracked or untracked. New files or files matching rules stated in the .gitignore file are untracked. Before a file or a modification of a file can be committed it has to be added to the index. This state is also named staged.
