Version control is the backbone of modern software development — and in 2025, Git and GitHub are more powerful (and beginner-friendly) than ever.
Whether you're solo-building side projects or collaborating in massive open-source ecosystems, this guide helps you use Git & GitHub faster and smarter.
🔍 What is Git?
Git is a distributed version control system that helps you:
- 📝 Track changes in your code
- 🕰️ Revert to previous versions
- 🤝 Collaborate with others without conflict
✅ Think of Git as a time machine for your code.
# Initialize a new Git repo
$ git init
# Save your changes
$ git add .
$ git commit -m "Initial commit"
🌐 What is GitHub?
GitHub is a cloud platform where your Git repositories live online. It enables:
- 👥 Team collaboration
- 🛠️ Issue tracking and discussions
- 🔁 CI/CD pipelines
- 📂 Hosting portfolios and docs
✅ Think of GitHub as social media for developers — but focused on code.
# Connect local Git repo to GitHub
$ git remote add origin https://github.com/your-username/repo.git
$ git push -u origin main
