Git Tutorial: Core Concepts, Branching & Merging

Git Masterclass: How Git Works in Production (Part 1) 👉 GitHub Repository: https://github.com/CloudWithVarJosh/G... 👉 Git Playlist:    • Git Masterclass   👉 Join the Channel to support:    / @cloudwithvarjosh   In this masterclass, we go beyond basic commands and build a deep understanding of how Git actually works under the hood. This is Part 1 of the Git Masterclass series, where we focus on core concepts, internal architecture, and the mental models required to use Git confidently in real-world environments. This is not just about learning commands. By the end of this session, you will not just use Git, you will understand how Git works. 🛠 What You’ll Learn Why Git is critical in modern engineering (DevOps, IaC, GitOps) Git architecture: working directory, staging area, local repository What a commit really is (immutability, snapshots, history graph) How .gitignore works and common pitfalls Branching: concepts, pointers, and parallel development Atomic development for clean commits and branches Fast-forward and three-way merges What actually happens during a merge Merge conflicts: why they occur and how to resolve them Renaming branches and default branch configuration Undoing changes with git reset and git revert ⏰ Timestamps 00:00:00 Introduction 00:01:45 Why Git?
