Description

Git (the version control system) is one of the main instruments in a toolkit of any developer. Regardless of the area of development you choose, all programmers work with the source code for projects that are constantly updated, changed, and deleted. In this free beginner's course on Git, you'll learn how to properly manage this process, easily recover from bugs, examine your change history, and how to maintain collaborative development.
