📖 Introduction

Git is a powerful distributed version control system that helps developers track changes in their code, collaborate effectively, and maintain a history of modifications. GitHub enhances Git by providing a cloud-based hosting service, enabling teamwork, issue tracking, and code sharing.

💡 Why Use Git and GitHub?

✅ Version Control: Keep track of every change in your project. ✅ Collaboration: Work seamlessly with teams across the globe. ✅ Backup & Security: Securely store your code in remote repositories. ✅ Efficient Workflow: Branching, merging, and pull requests make development structured and organized.

dpkg -l | grep git   # Check if Git is already installed
sudo apt update
