Course brief

A rigorous distributed version-control curriculum for modern delivery teams.

This 26-chapter, 130-lesson course develops Git from first principles before moving into production collaboration and repository operations. It emphasizes beginner-first mental models, observable repository state, safe disposable labs, recovery-aware workflows, security and integrity controls, large-repository operation, automation, CI/CD, GitOps, and production governance.

By the end

You will be able to

  • Understand Git’s object model, index, refs, commit graph, remotes, and distributed architecture
  • Design safe branch, merge, rebase, release, and collaboration workflows
  • Recover lost work and investigate regressions using Git’s forensic and history tools
  • Secure repository history, credentials, signatures, sensitive data, and trust boundaries
  • Operate Git efficiently in large repositories, CI/CD pipelines, migrations, release automation, and GitOps systems

Complete syllabus

26 chapters in prerequisite order.

The sequence goes beyond command references and feature lists. It progresses from distributed-version-control foundations through Git internals, collaboration, history editing, recovery, release engineering, repository composition, large-repository operation, forensics, security, maintenance, migration, CI/CD, GitOps, and a production capstone.
