# GitHub

> GitHub is a developer platform for building, shipping, and maintaining software. It provides cloud-based Git repository hosting, CI/CD via GitHub Actions, project management with Issues and Projects, code review via pull requests, AI-powered development with GitHub Copilot, and APIs (REST and GraphQL) for automation and integration.

GitHub documentation is available at https://docs.github.com. The content covers GitHub.com (cloud), GitHub Enterprise Server, and GitHub Enterprise Cloud. Unless otherwise noted, links below point to docs.github.com.
