GitHub is a web-based platform for version control using [Git](../../dev/Git.md). It provides a collaborative environment for developers to work on projects, manage source code, and track changes. Additionally with GitHub Copilot it offers a AI based language model to help with coding. You have the option to automate with [GitHub Actions](GitHub%20Actions.md).
