Git fundamentals

Included in the course

What you'll learn

• Develop according to the latest engineering practices
• Effectively manage source code, add it to the public repository, and analyze and modify history
• Work with GitHub and contribute to open-source projects

Description

Git (a version control kit) is one of a developer's many important tools. Regardless of the area of development you choose, all programmers work with source code for projects that are constantly updated, changed, and deleted. In this free beginner's course on Git, you'll learn how to manage this process properly, how to deal with bugs, how to examine your change history, and how to maintain collaborative development.
