> Git has an elegant and powerful underlying model based on a few simple concepts: Commits are immutable snapshots of the repository Branches are named sequences of commits Every object has a unique ID, derived from its content I would list them as: Every object has a unique ID, derived from its content - and every commit id depends on its ancestors' commit ids Each commit has an associated snapshot (file tree) of the repository A branch is a named reference to a commit - the referenced commit changes with addition/rebase/amend of commit(s) Not quite as compact or elemental but a usably granular mental model. If you want to learn how git works you can read about it, or merely look at the small text files inside a .git directory.
