Git is a tool that helps developers keep track of changes they make to their projects’ source code over time. It creates a history of the changes and who made them, so developers can work together without messing up each other’s work.

With Git, developers can work on their own copies of the project and then merge their changes back into a main version when they’re done. Git also helps resolve conflicts between different changes made by different developers, and allows developers to roll back changes to previous versions of the project’s source code.
