Core Concepts

• Distributed: Every clone is a full repository — no central server required
• Snapshots, Not Deltas: Git stores full snapshots of the project at each commit, not file-based changes
• Three States: Modified (working directory), Staged (index), Committed (HEAD)
• Content-Addressable: All objects stored by SHA-1 hash of content — integrity guaranteed
• Nearly Every Operation Is Local: No network needed for most operations
• Branches Are Cheap: A branch is just a lightweight pointer to a commit
• Data Integrity: Checksumming (SHA-1) ensures data can't be corrupted without detection
• Staging Area: The index allows granular control over what goes into each commit
• Distributed Workflows: Centralized, integration manager, dictator/lieutenants models
• Porcelain and Plumbing: High-level user commands and low-level scripting commands
