Version control is a critical aspect of modern software development, and Git has become the go-to tool for managing code changes in a collaborative environment. Whether working on individual projects or as part of a team, Git provides a robust system for tracking changes, managing different versions of code, and ensuring that collaboration runs smoothly. With its distributed nature, Git allows developers to work on code independently, merge their changes seamlessly, and maintain a complete history of every modification. This chapter will introduce the core concepts and fundamental workflows of Git, helping new and experienced developers understand how to use it effectively.
