Introduction to Git & GitHub

👋 What is Git?​

Git is a powerful Version Control System (VCS) that helps developers track and manage changes in their code.
It allows you to save different versions of your project, view your history, and go back to earlier versions whenever needed.

Think of Git as a time machine for your code — you can move backward or forward through your project’s history without losing any work.

💡 In simple words: Git helps you keep track of every change in your code and makes teamwork easier.

🌐 What is GitHub?​

GitHub is a web-based platform that works with Git to store your code online and help you collaborate with others.
It’s like a social platform for developers where you can upload your code, contribute to other projects, and showcase your work.

Using GitHub, you can:

  • Store your Git repositories safely in the cloud
  • Collaborate with teammates from anywhere
  • Contribute to open-source projects
  • Share your work with others easily

💬 In short: GitHub is an online home for your Git projects — a place for sharing, learning, and teamwork.
