🔍 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
