Git & GitHub for Version Control

Version control, also known as source control, is the practice of tracking and managing changes made to the source code and configuration of a project over time, through the use of a software called a version control system (VCS).

It allows developers to maintain a complete history of all changes made to a project, to compare those changes between them, and to revert them back to a previous state if needed.

Together, Git and GitHub form the foundation of many professional development workflows, from tracking your own work to collaborating with a team through branches, commits, and pull requests.

Learning objectives

In this module, you'll learn how to track and manage changes to a codebase with Git and collaborate with other developers through GitHub.

After completing this module, you will be able to:

• Track changes to a project using Git commits.
• Navigate and compare previous versions of a codebase.
• Restore, revert, and reset unwanted changes safely.
• Develop changes independently using branches and merge them back together.
• Temporarily store unfinished changes using the Git stash.
• Connect local Git repositories to remote repositories hosted on GitHub.
• Push and pull commits between local and remote repositories.
• Create and review pull requests as part of a collaborative development workflow.
