-Local release builds are signed with the debug key so they install over each other. Published releases will use a dedicated signing key.
+Release builds are signed with the project key from `~/.android/nogoogleapps-release.properties` (kept outside the repository); without it they fall back to the debug key for local testing. `scripts/release.sh <app>` builds, signs and publishes a release in the format Obtainium expects.
