Understanding the 3-Zone Model and Version Control | Git & GitHub Training #3
In this third video of the Git & GitHub training, we explore Git's three-zone model, the most important concept for understanding how Git works.
Before manipulating commands, it's essential to understand how Git manages changes. We'll also see what a version control system is, why it's indispensable in software development, and how Git allows you to track a project's evolution over time.
By the end of this video, you'll understand why modifying a file, preparing it with `git add`, and creating a commit with `git commit` are three completely different actions.
📚 On the agenda:
What is a version control system?
