Introduction to GitHub
What is GitHub?
GitHub is a powerful platform for version control and collaborative software development. As a web-based Git repository hosting service, it enables developers to store, manage, track, and control code changes efficiently. GitHub supports distributed version control and provides essential tools for code hosting, collaboration, and project management.
Core Concepts of GitHub
Version Control System
