Git Learning Guide

Git is a free, open-source distributed version control system and one of the most popular version control systems today, widely used in many software projects. This book is a practical Git guide for professional developers, divided into 26 chapters that proceed from basic concepts to introduce Git's operations and usage techniques step by step. It opens by explaining what distributed means: how repositories become the foundation of distributed collaboration and why creating and merging branches is so simple. It then uses a first Git project to guide readers through getting started—creating a repository, making the first commit, checking status, committing changes, and showing history—and demonstrates collaboration features such as cloning repositories, shared repositories, push, and pull. Building on that foundation, the book analyzes the nature of commits and the management of multiple commits, explains core concepts such as commits, repositories, branches, merging, and rebase, and further covers practical scenarios including workflow design, branch-based development, binary search debugging, release delivery, splitting and merging projects, and project migration. The book uses numerous examples to demonstrate how to use major Git commands and is organized with "getting started tutorials" and "step-by-step instructions" for easy reference, helping readers understand how Git actually works and use commands correctly and well in agile team development.
