Git Will Finally Make Sense After This (4 Hours)

A 4-hour deep dive into how Git actually works — from the building blocks up. No memorization. No "10 commands every developer needs to know." Just understanding. By the end, you'll know exactly how Git stores your work, how branches and references really function, and how to reason about every command you run. 🚀 This is the first 4 hours of my complete Git & GitHub course on Udemy: 👉 https://www.udemy.com/course/git-in-p... ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎓 WHAT YOU'LL LEARN ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📦 Git's three building blocks — blobs, trees, and commits ⤴︎ The three references — HEAD, branches, and tags 🌳 The three-tree model — work tree, index, and HEAD 🔧 Branching, resetting, and the reflog 📚 How to read Git's documentation 🧠 Why understanding beats memorization in the age of AI ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 👥 WHO THIS IS FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Self-taught developers who use Git daily but still feel uncertain when something goes wrong • Bootcamp grads and CS students preparing for their first dev job • Engineers who've been faking it on Git for years and want to finally understand it • Anyone tired of pasting commands from Stack Overflow and AI without knowing what they do ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📁 RESOURCES — STARTER FILES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ All the demo projects, setup scripts, and exercises used throughout this video: 👉 https://github.com/KianAttar/git-star...
