Copilot Adds a First-Pass Map for Unfamiliar Repositories

GitHub now offers Copilot-generated overviews on repositories a user has not contributed to before. The summary draws from repository context to describe purpose, technologies, and contribution guidance, with shortcuts for recent changes and ways to contribute. GitHub says the feature is available across all Copilot plans; maintainers should still treat a generated overview as orientation, not a substitute for authoritative project documentation.
