Commit & Staging Workflow
Git Commit & Staging manages the 3-stage Git pipeline (Working Directory -> Staging Area / Index -> Local Repository Commit History), capturing immutable snapshots of your project.
Real-world analogy: Photo Snapshot Album
Working directory changes are like objects on a stage. Running 'git add' places items in front of the camera lens (Staging Index). Running 'git commit' snaps a permanent photo stored in your album.
- Working Directory= Local directory files modified on disk.
- Staging Index= Pre-commit buffer holding files staged for the next snapshot.
- Repository Commit= Permanent 40-character SHA-1 checksum snapshot stored in HEAD history.

Git Workflow Metadata
Keep your commits small, focused, and frequent! Write clear imperative commit messages (e.g. 'add user login endpoint' instead of 'fixed stuff').
