GitHub is a web-based platform for software development and version control using Git. It is primarily used by developers, teams, and organizations to host, review, and manage code for projects of any size. The service facilitates collaboration, allowing multiple people to work on the same codebase efficiently.

• Version Control with Git: Tracks every change made to a project's code, creating a complete history that can be reviewed or reverted. This allows developers to experiment freely without breaking the main project.
• Collaborative Code Review: Enables team members to discuss proposed changes through pull requests before they are merged into the main codebase, improving code quality and shared knowledge.
• Project Management Tools: Includes built-in issue tracking, project boards, and wikis to help teams organize tasks, track bugs, and document their work alongside the code.
• Code Hosting and Discovery: Provides a central place to store repositories, making code accessible from anywhere. It also serves as a vast public directory where developers can discover, reuse, and contribute to millions of open-source projects.
• Automated Workflows: Supports automation through GitHub Actions, allowing teams to build, test, and deploy their code directly from the platform, reducing manual work and standardizing processes.
