Course Description

Version control is one of the most practical skills you can add to your developer toolkit, because it turns messy file edits into a clear, recoverable history. In this free online course, you’ll learn how Git helps you work with confidence: seeing exactly what changed, when it changed, and why it changed, so you can experiment without fear and move faster on real projects.

Rather than treating Git as a list of commands to memorize, the course builds intuition around how versions are created and how a repository keeps a dependable record of your work. You’ll practice reading differences between files, reviewing history, and understanding how commits connect to the story of a project. That foundation makes it easier to diagnose problems, pinpoint where a bug was introduced, and return to a stable state when something breaks.

Collaboration is where Git and GitHub become essential. You’ll explore branching strategies that support teamwork, learn how to merge changes back together, and understand what happens when conflicting edits collide. The course guides you through resolving merge conflicts with a calm, structured approach, so collaboration stops being intimidating and becomes a repeatable process you can rely on in professional environments.

You’ll also set up a productive workspace across operating systems, work with repositories locally, and connect your work to remotes to keep projects in sync across machines or teammates. By the end, you’ll be comfortable navigating a repo, staging and committing changes, using logs to audit progress, and managing branches and merges with clarity—skills that translate directly to real-world development, code reviews, and team delivery.
