+MoasdaWiki App ist eine Erweiterung zum MoasdaWiki-Server, um eine Kopie deiner Wikiinhalte auf deinem Mobilgerät zu haben.
+
+Funkionalitäten:
+
+- Synchronisiert die Inhalte von einer MoasdaWiki-Server-Instanz.
+- Datenschutz: Es wird keine Cloud-Verbindung hergestellt, verbindet sich direkt mit dem Server in deinem privaten Netzwerk.
+- Kalender-Integration, zeigt Geburtstage und Termine im Kalender des Mobilgeräts (nur in der deutschen Version).
+
+Synchronisieren des Inhalts mit einem MoasdaWiki-Server:
+
+1. Lade MoasdaWiki-Server von https://moasdawiki.net/ herunter.
+2. Setze eine MoasdaWiki-Server-Instance in deinem LAN auf.
+3. Installiere und öffne die MoasdaWiki-App.
+4. Du kannst einen Hinweis sehen, dass die App zunächst konfiguriert werden muss. Drücke auf den Hinweis.
+5. Drücke auf "Hostname" und gib den Hostnamen der Server-Instanz ein, z.B. `192.168.1.101`. Drücke OK.
+6. Im Statusbereich darunter solltest du nun "Erfordert Berechtigung am Server" sehen. Andernfalls prüfe erneut Hostname und Port.
+7. Öffne auf der Serverseite die Wikiseite im Browser, klicke auf "Hilfe" und "Synchronisierung".
+8. Du siehst eine Liste von Geräte und Synchronisierungs-Sitzungen. Überprüfe den Gerätenamen und klicke auf "Erlauben".
+9. Zurück in der App drücke den Zurück-Button (←) in der Ecke links oben, um zum Hauptdialog zurückzukommen. Nun kannst du einen Hinweis sehen, dass die App synchronisiert werden muss. Drücke auf diesen Hinweis.
+10. Nun solltest du alle Inhalte des Servers auch in der App haben und die Wikiseite "Startseite-App" sehen.
+
+Hinweis: Der Wikiinhalt kann nicht in der App modifiziert werden, da es keinen Spaß macht Wiki-Syntax auf dem Mobilgerät zu tippen. Änderungen müssen über den MoasdaWiki-Server erfolgen.

+MoasdaWiki App is an extension of the MoasdaWiki Server to have a copy of your Wiki content on your mobile device.
+
+Features:
+
+- Synchronizes the data from a MoasdaWiki Server instance.
+- Data privacy: No cloud connection established, directly connects to the server inside your private network.
+- Calendar integration, shows birthdays and events in the mobile calendar (German version only).
+
+Synchronize content with a MoasdaWiki Server:
+
+1. Download MoasdaWiki Server from https://moasdawiki.net/.
+2. Set up a MoasdaWiki Server instance in your LAN.
+3. Install and open the MoasdaWiki App.
+4. You can see a hint that the App has to be configured first. Press on that hint.
+5. Press on "Host name" and enter the host name of the server instance, e.g. `192.168.1.101`. Press OK.
+6. In the status section below you should see "Needs authorization at server". Otherwise check host name and port again.
+7. On server side open the Wiki page in a browser, click on "Help" and "Synchronization".
+8. You can see a list of devices and synchronization sessions. Check the device name and click on "Grant".
+9. Back in the app press the back button (←) on the upper left corner to get back to the main dialog. Now you can see a hint that the app has to be synchronized. Press on that hint.
+10. Now you should have all the server content also in the app and you can see the "Home-App" wiki page.
+
+Hint: Content cannot be modified within the app as it is no fun to type Wiki syntax on the mobile device, changes have to be done via the MoasdaWiki Server.
