+- **`adminPassword`**: Passwort für die Terminverwaltung unter `/admin`. Ändere den Standardwert `change-me`, bevor du die Anwendung veröffentlichst.
 - **`activities`**: Liste von Objekten mit `name`, `icon` (Unicode Emoji) und `type` (`short` oder `long`).
 - **`availableDates`**: Liste von verfügbaren Tagen mit `date` (`YYYY-MM-DD`) und `type` (`short` oder `long`).
 - **`names`**: Optional vordefinierte Namen zur Auswahl (ist die Liste leer, wird ein Standard-Fallback angeboten).

+Die Terminliste lässt sich auch über die passwortgeschützte Verwaltung unter `http://localhost:8080/admin` bearbeiten. Das Passwort bleibt dabei auf dem Server und wird nicht an Besucher ausgeliefert.
+
+Bei Docker Compose werden `appsettings.json` und `booked_dates.json` dauerhaft unter `/docker/data/date` gespeichert. Beim ersten Start legt der Container die Einstellungen dort aus der im Image enthaltenen Vorlage an. Ändere danach den Standardwert `change-me` in `/docker/data/date/appsettings.json` oder übernimm vor dem ersten Start eine vorbereitete Konfigurationsdatei.
