📖 Introduction

Welcome to Git & GitHub Mastery! This repository is a complete, self-paced curriculum that takes you from absolute beginner to advanced Git expert.

Git is the most widely used version control system in the world, and GitHub is the largest host of source code. Whether you are a student, a freelancer, or a professional developer, mastering Git & GitHub is a non-negotiable skill.

What makes this course different?

  • 🟢 Beginner Examples — Real-life analogies and simple commands for newcomers.
  • 🔵 Expert Examples — Professional, team-based scenarios for experienced developers.
  • ⚠️ Warnings — Common mistakes and how to avoid them.
  • 💡 Pro Tips — Insider knowledge and best practices.
  • 🗺️ Visual diagrams — Mermaid and ASCII art to build mental models.

🎯 Prerequisites

  • A computer (Windows, macOS, or Linux) with internet access.
  • Basic comfort with the command line / terminal (navigating folders, running commands).
  • No prior Git experience required — we start from zero.
  • Curiosity and a desire to practice! Git is learned by doing, not just reading.

🛠️ How to Use This Repository

  1. Start at Part 1 and work your way through the parts in order — each part builds on the previous one.
  2. Follow along in your terminal. Type every command yourself; muscle memory matters.
  3. Choose your level per concept. If you are new, read the 🟢 Beginner example first. If you are experienced, jump to the 🔵 Expert example.
  4. Use the Cheat Sheet when you need a quick command reference.
  5. Follow the Command Sequence when you want to see the full real-world workflow end to end.
  6. Each part ends with a "Next Steps" section that links you forward.
