What is GitHub?
GitHub is the largest host of source code and the de facto standard for collaborative software development. It wraps Git in pull requests, code review, and branch protection, then adds Issues, Projects, and Discussions for planning, Actions for CI/CD and automation, Codespaces for browser-based dev environments, and Copilot for completion, chat, and agent-driven pull requests. Public and private repositories are free with generous limits; paid Team and Enterprise plans add more Actions minutes, advanced security scanning, and organisation controls.
For anyone shipping software — or publishing prompts, skills, and design assets — it is also where the surrounding ecosystem expects your work to live, since most tools authenticate against a GitHub account.

FAQs
Common questions about GitHub
Is GitHub free?
Yes. Unlimited public and private repositories are free, including Actions minutes and Codespaces hours on a monthly allowance. Team and Enterprise plans add more capacity, advanced security, and organisation controls.
Do I need to know Git to use it?
Not for everything — files can be edited, reviewed, and merged in the browser or the desktop app. Git knowledge helps once you work across branches locally.
What is GitHub Actions?
Built-in CI/CD: workflows defined in YAML that run on pushes, pull requests, schedules, or manual triggers — used for tests, builds, deploys, and scheduled automation.
