Git — Distributed Version Control In-Depth Reference
Comprehensive reference for Git internals, concepts, and workflows. Covers the object model, reference system, index, branching/merging, remotes, configuration, hooks, and plumbing commands.
Data Flow
Working Tree
↕ (git add / git checkout)
Index (Staging Area)
↕ (git commit / git reset)
Object Store (.git/objects/)
↕ (git pack / git gc)
Packfiles (.git/objects/pack/)
↕ (git fetch / git push)
