In today’s digital world, building software isn’t a solo journey, it’s a team effort. Whether you're developing a small website or managing a large-scale application, version control is your best friend. This is where Git and GitHub come into play.

🔧 What is Git?

Git is a free, open-source version control system created by Linus Torvalds, the same person who built Linux. Git helps you track changes in your code, revert to previous versions, and collaborate with others without overwriting each other’s work.

Imagine writing a long essay. Git allows you to save versions of your draft at different stages. If you mess up, you can go back to a cleaner version without starting over.

Key Features of Git:

    • Local repository: Work offline without internet access.
    • Branching and merging: Try out new features safely, then merge when ready.
    • History tracking: Know what changed, when, and who made the change.
    • Speed: Git is fast, even for large projects.



🐙 What is GitHub?

GitHub is a cloud-based platform that hosts your Git repositories online. It provides tools for collaboration, project management, code review, and even CI/CD (Continuous Integration/Continuous Deployment).

While Git is a tool that runs on your computer, GitHub is a website where you can share your Git-tracked projects with the world.

Why Use GitHub?

    • 🧑‍🤝‍🧑 Collaborate with teammates easily
    • 🗂 Store and manage code in the cloud
    • 🔄 Track bugs, suggest features, and handle pull requests
    • 🌍 Showcase your work to potential employers
