GitHub Copilot has grown well beyond code completions in your editor. It now lives in your terminal, too. GitHub Copilot CLI lets you review code, generate tests, debug issues, and ask questions about your projects without ever leaving the command line. To help developers get up to speed, we put together a free, open source course: GitHub Copilot CLI for Beginners. It’s 8 chapters, hands-on from the start, and designed so you can go from installation to building real workflows in a few hours.
