Git Concepts¶
Git is a Distributed Version Control System.
A version control system saves the state of current source files.
Every state is stored in a snapshot, the so called commit.
The commits form a directed acyclic graph.
Git uses different objects to store information
Every git object is identified by a hashsum, a SHA-1 hash.
To not having to remember hashes when referring to commits, git provides references.
All git information about a repository is contained in a single
.gitdirectory
