It is part of the DevOps Bootcamp learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
What is Version Control?
Ever ended up with report_final, report_final_v2, report_final_FINAL? A Version Control System (VCS) kills that mess — it is a smart undo button for your whole project.
Chaos Without VCS
Without a VCS, teamwork falls apart: people overwrite each other, changes vanish, bugs are impossible to trace, and there is no history of who did what.
How VCS Helps
A VCS keeps the full history of every change. You can see who did what and when, roll back to any state, and merge everyone’s work without stepping on toes.
Types of Version Control
There are two flavors of version control: centralized (CVCS) and distributed (DVCS). They differ in where your project history actually lives.
Centralized VCS Explained
A centralized VCS keeps all history on one server — you check files out and back in. The catch: if that server goes down, nobody can commit or read history. Think SVN, Perforce.
Distributed VCS (DVCS)
A distributed VCS gives every developer a full copy of the entire history locally. You commit offline and share when ready — exactly where Git shines.
Git: A Distributed Powerhouse
Git is the world’s most popular distributed VCS. Linus Torvalds built it for speed, data integrity, and the messy non-linear workflows real teams need.
Why Git Stands Out
Git’s distributed design pays off: commit offline, blazing-fast local operations, no single point of failure, and flexible branching and merging.
Git's Local Repository
The key idea is the local repository. Clone or init a project and you get its full history on your machine — which is why Git operations feel instant.

Recap & Next Steps
Nice! You now get why a VCS matters, how centralized differs from distributed, and why Git leads the pack. Next up: installing and configuring Git.
