01. What is Version Control
Gitfinal L1 01 Welcome
I just said "version control". Now since you're in this course, you might already know a bit about version control. But if you don't, a handy trick I've learned is to try reading the words in reverse - so "version control" would become "control version"! So a Version Control System is just software that helps you control (or manage) the different versions…of something (typically source code).

Recap
Remember that the main point of a version control system is to help you maintain a detailed history of the project as well as the ability to work on different versions of it. Having a detailed history of a project is important because it lets you see the progress of the project over time. If needed, you can also jump back to any point in the project to recover data or files.
In this course, we'll be using Git which is a distributed version control system. You might be surprised to discover that you're already using version control all the time!
