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.
๐ What Youโll 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

Out of curiosity, I checked your subscriber count I usually follow creators who put out genuinely useful content and like to see how they grow over time. Seen quite a few reach millions, and honestly, I feel your channel will get there too. Keep going, mate!
Good call on covering the basics first. For Part 2, hoping to see how you handle real GitHub workflowsโboth new projects and existing ones. Stuff like:
*Single source of truth*
- Branch structure & protection rules that actually make sense
- Configs, IaC, everything in one place
*CI/CD hooks*
- Webhooks, secrets per environment, status checks
- Making sure broken code doesn't slip through
*Team stuff*
- PR templates, project boards, clean access controls
- Branch workflows that don't cause chaos with multiple teams
*Existing projects*
- Retrofitting best practices without breaking things
- Moving configs and manifests into Git properly
Simple, solid, ready for real-world. Looking forward to it! ๐
