 ## Releases
 
 `.github/workflows/release.yml` builds the APK with `--version` set to the
 release version and publishes it alongside the macOS/Windows/Linux builds as
-`PokemonRed-<version>-android.apk`.
+`gen1recomp-<version>-android.apk`.
 
 ## Signing
 
-Signed with the default Android keystore (no setup required).
+Production APKs are built with `scripts/build_android.sh --release`. They must
+be signed with the same long-lived certificate as the currently installed app:
+Android's Package Installer rejects an update with a different signing
+certificate. Store that keystore and its passwords only in CI secrets, expose
+them as `GEN1RECOMP_ANDROID_KEYSTORE`,
+`GEN1RECOMP_ANDROID_KEYSTORE_PASSWORD`, `GEN1RECOMP_ANDROID_KEY_ALIAS`, and
+`GEN1RECOMP_ANDROID_KEY_PASSWORD`, and never commit the keystore. A newly
+created certificate cannot update users who have an APK signed by a different
+legacy key; those users need one final manual reinstall before in-app updates
+can take over.
