GitHub is a web-based platform for version control and collaboration, primarily used by developers and teams to build software. It provides a central place to store, manage, track, and collaborate on code changes.

• Version Control with Git: Tracks every change to code, allowing developers to revert, branch, and merge projects safely.
• Pull Requests and Code Review: Enables team collaboration through proposed changes that can be discussed and reviewed before merging.
• Project Management Tools: Includes integrated issue tracking, project boards, and wikis to organize work alongside code.
• Actions for Automation: Allows the creation of custom workflows to automatically build, test, and deploy code.
• Extensive Code Hosting: Serves as a public and private repository host for millions of open-source and private projects.
