Ask Copilot for a repository overview
TL;DR
GitHub Copilot can now generate a high-level overview for repositories you are exploring for the first time or have not contributed to before on github.com. On the repository home page, Copilot suggests the action 'Give me a high-level overview'. Copilot Chat gathers repository context and summarizes purpose, technologies, and contribution guidelines.
Nauti's Take
Run it first on three repositories you already know well: if Copilot gets the entry point, build steps, and contribution rules right, it can save onboarding time. If it misreads architecture or setup, treat the overview like AI-generated code comments: useful for orientation, but something to verify before making decisions.

For developers, this mainly saves orientation time in unfamiliar codebases: instead of manually scanning the README, folder structure, and contributing files, they get an initial map directly inside the repository. The weak point is still context quality. Copilot can speed up onboarding, but it does not replace checking build scripts, tests, open issues, and security rules.
