Course details

Version control—the practice of tracking and managing changes to software code—is one of the most powerful tools a developer can wield. And Git has become the version control system of choice for the modern web. The concepts of Git are not hard to understand, especially for developers, but Git has a language of its own. What is rebasing? What is a detached head? In this beginner-level course, Morten Rand-Hendriksen provides a common-sense translation and breakdown of the terminology of Git, and shows how you can use Git to travel back in time in a way that’s practically science fiction (at least when it comes to code). Morten gives you the base-level knowledge you need to get started with Git, detailing important terminology and functions, and shows how to resolve common issues developers face in version control.
