In this tutorial, we will install Git on AlmaLinux 10. Git is a free and open-source distributed version control system. It was created by Linus Torvalds(The inventor of the Linux Operating System) for version control in the development of the Linux kernel. Git is designed to track changes in code and other files throughout the software development process. Git offers a variety of features, including a distributed architecture, version control, snapshots, branching, merging, and collaboration. We can describe Git as a “time machine” for our code, because it allows us to revert changes and manage different versions of a project from its creation to the latest version.

Git can be installed on AlmaLinux 10 in two ways: either from the default repository or by building it from source.
