# Packaging and updates

`Decky.appinstaller.template` is the stable update-feed template. The release
pipeline will replace its placeholders after producing and signing a versioned
MSIX bundle.

The final `PUBLIC_BASE_URL` must be an HTTPS location that Windows App Installer
can read without an interactive sign-in. Package name and publisher must remain
stable across releases, and `VERSION` must be a monotonically increasing
four-part MSIX version such as `1.2.0.0`.

The application project is temporarily configured as unpackaged so the first
read-only shell can be developed before signing identity and public artifact URL
are chosen. MSIX packaging becomes the release configuration, not a different
application or update mechanism.
