Git and GitHub Tutorial 2026 – Complete Beginner Guide
Git and GitHub are essential tools in modern software development. Whether you are a student, beginner, or professional developer, learning Git and GitHub helps you manage code efficiently, collaborate with teams, and build a strong developer portfolio.
🔍 What is Git?
Git is a distributed version control system (VCS) that tracks changes in your source code and allows multiple developers to work on the same project safely.
- Tracks file changes
- Allows rollback to previous versions
- Supports team collaboration
Each time you save your work using Git, it creates a snapshot called a commit. If something goes wrong, you can easily restore a stable version.
☁️ What is GitHub?
GitHub is a cloud-based platform that hosts Git repositories online. It enables developers to store code, collaborate, and contribute to open-source projects.
In simple words, GitHub works like Google Drive for developers with advanced version control features.
- Cloud backup of code
- Team collaboration
- Issue tracking and pull requests
