Git is a version control system: it records the history of a project, so you can go back to any earlier version, see who changed what, and work in parallel with other people without overwriting each other. It was created in 2005 by Linus Torvalds for developing the Linux kernel, and today it is the standard tool for almost every software project.

Try it: press Save a new version a few times and compare the two folders. Then click an old commit in the "With Git" folder.

💬 In the "Without Git" folder, how would you know which file is the latest — or who changed what?
