microsoft/winget-pkgs/.github/copilot-instructions.md

This is the Windows Package Manager (WinGet) community repository — a manifest-only repo containing ~415,000+ YAML files describing how to install Windows applications via winget.

Each package version lives in manifests/<first-letter>/<Publisher>/<Package>/<Version>/ and requires three…
