Git Internals & Architecture: Build Git with Python

Have you ever used Git but wondered what actually happens behind the scenes when you run commands like git init, git add, or git commit?

Most tutorials teach how to use Git, but very few explain how Git actually works internally.

This course is different.

In this course, you will build your own version of Git from scratch using Python, step by step. By implementing Git yourself, you will gain a deep and practical understanding of how version control really works.

What Makes This Course Unique?

We don’t just explain Git — we build it
Learn Git internals through real implementation, not theory

Understand complex concepts like blobs, trees, commits, and branches clearly
Perfect for developers who want to move from Git user → Git expert

What You’ll Learn

By the end of this course, you will understand and implement:

• How git init works internally

• How Git handles files using Blobs & Git Objects

• The staging area and how git add really works

• How git commit creates commits and trees

• How branches are created, listed, and deleted

• How git checkout switches between branches

• How git log reads commit history

• How git status detects file changes

• How Git uses hashing and directory structure

• Building a CLI-based Git system using Python

Every topic is explained clearly, step by step, with real code so you don’t just memorize commands — you truly understand them.
