 Jak uruchomić

 Otwórz plik `index.html` w przeglądarce (najlepiej na urządzeniu mobilnym lub w trybie responsywnym).
+
+Signing a release APK/AAB
+------------------------
+
+Aby uniknąć ostrzeżeń "nieznany deweloper" lub instalatora na Androidzie, zbuduj podpisany pakiet APK lub AAB i zainstaluj go zamiast debugowego APK.
+
+1. Utwórz magazyn kluczy (jeśli go nie masz):
+
+```bash
+keytool -genkey -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my_key_alias
+```
+
+2. Skopiuj `gradle.properties.example` do swojego osobistego pliku `~/.gradle/gradle.properties` i uzupełnij wartości (nie commituj prawdziwych haseł do kontroli wersji).
+
+3. Zbuduj podpisany pakiet APK lub AAB:
+
+```bash
+./gradlew assembleRelease   # podpisany APK (jeśli podpisywanie jest skonfigurowane)
+./gradlew bundleRelease     # AAB do Sklepu Play
+```
+
+4. Zainstaluj APK za pomocą adb:
+
+```bash
+adb install -r app/build/outputs/apk/release/app-release.apk
+```
+
+Lub przesłać AAB do Google Play (testowanie wewnętrzne) — zalecane w celu najłatwiejszej dystrybucji.
+
+Jeśli chcesz tylko przetestować lokalnie i zobaczyć ostrzeżenie "Nieznane źródła", możesz tymczasowo włączyć instalowanie z nieznanych źródeł na urządzeniu, ale dystrybucja podpisanego wydania jest bezpieczniejszym podejściem.
