GitHub is a web-based platform for software development that provides version control using Git. It is used by developers and teams to host, manage, and collaborate on code projects. The service facilitates project tracking, code review, and community contribution for open-source and private software.

• Version Control with Git: Tracks all changes to code, allowing developers to revert to previous states, branch for new features, and merge updates.
• Collaboration Tools: Includes pull requests for proposing and discussing code changes, and issue tracking for managing bugs and tasks.
• Project Discovery: Hosts millions of public repositories where developers can find, use, and contribute to open-source software.
• Automated Workflows: Supports automation through GitHub Actions for building, testing, and deploying code directly from the platform.
• Access Controls and Security: Offers granular permissions for teams and includes features for vulnerability scanning and secret detection to improve code security.
