English

中文

Git is not suitable for learning by memorizing commands.

A more effective way is to build capabilities based on real work scenarios.

Phase 1: Establishing a Mental Model

First, understand the four areas:

working tree -> index -> local repository -> remote repository

Recommended reading:

1. Git Mental Model
2. Snapshots and State: HEAD, Index, and Working Tree
3. The Object Graph: Blobs, Trees, and Commits
4. The Index Is the Next Commit Draft
5. Git Basic Commands
6. Why Use Git

Mastery Goals:

• Understand git status.
• Know the relationship between git add and git commit.
• Distinguish different versions in HEAD, the index, and the working tree.
• Explain how a path resolves through commits, trees, and blobs to file content.
• Know the difference between local commit and remote push.

Phase 2: Daily Development

Recommended reading:

1. Everyday Git Commands
2. Branch and Merge
3. Rebase vs Merge
4. Stash

• Know when to use stash.
• Know the risks of local rebase and public history.

Phase 3: Team Collaboration

Recommended reading:

1. Team Git Workflow Guide
2. Pull Request Best Practices
3. Code Review Best Practices

Mastery Goals:

• Can write reviewable PRs.

• Prioritize revert for public commits.
• Preserve the current state before executing high-risk commands.

Phase 5: Git in the AI Programming Era

Recommended reading:

1. AI Native Git Workflow
2. AI Generated Code Review
