 # sky_phone
 
+## Custom Apps
+
+`sky_phone` erkennt Registrierungen gestarteter Fremd-App-Ressourcen über integrierte
+Hersteller-Aliase und übernimmt unterstützte Apps automatisch in Springboard und App Store. In
+App-Ressourcen müssen dafür keine Sky-Vorlagen abgelegt werden. Unterstützt werden die
+dokumentierten Basisverträge von LB Phone, 17Movement, High Phone, Quasar Smartphone V3 und
+YSeries; die Resource- und Cfx-Export-Aliase `lb-phone`, `17mov_Phone`, `high-phone`,
+`qs-smartphone` und `yseries` werden direkt von `sky_phone` bereitgestellt. Einrichtung und
+ehrliche Kompatibilitätsgrenzen stehen in der
+[deutschen Custom-App-Anleitung](docs/custom-apps.md).
