This book follows a 7-chapter progression: understand AI risks → grasp concepts → set up your environment → operate the terminal → learn commands → practice locally → apply with AI agents. Each chapter builds directly on the previous one. By starting with concrete risks of AI code generation in Chapter 1, every Git operation you learn has a clear "why." After completing this book, you will be able to manage version control locally with Git and safely handle code generated by AI agents like Claude Code using branches and commits.
