+<h3>Welche Links können mit dieser App verwendet werden?</h3>
+<p>Alle Facebook-Subdomains werden unterstützt, ob mobil (m.facebook.com) oder sprachspezifisch (de-de.facebook.com). Der Link muss eine Ereignis-ID enthalten.<br />Wie kann diese Anwendung verwendet werden?</p>
+<h3>Wie kann diese Anwendung verwendet werden?</h3>
+<ul>
+    <li><strong>Einfügen-Knopf</strong>: Fügen Sie einen kopierten Link aus der Zwischenablage in die URL-Leiste ein.</li>
+    <li><strong>Teilen mit</strong>: Eingebaute Android-Freigabefunktion, z.B. von einem Browser aus.</li>
+    <li><strong>Öffnen mit</strong>: Die in Android eingebaute öffnen-mit-Funktion, z.B. beim Klicken auf einen Link in einem Messenger.</li>
+</ul>
+<h3>Warum funktioniert die Veranstaltung X nicht?</h3>
+<p>Diese Anwendung greift auf öffentlich zugängliche Ereignisinformationen zu. Wenn die Veranstaltung z.B. den Ort ohne Login nicht anbietet, ist dies in dieser Anwendung nicht verfügbar. Auch bieten einige Veranstaltungen die Informationen einfach nicht in einem maschinenlesbaren Format an. Veranstaltungen mit mehreren Instanzen sind problematisch, da sie beim Scraping von m.facebook.com nicht das korrekte Start- und Enddatum angeben.</p>
+<p>Wenn Sie Probleme mit einem bestimmten Ereignis haben, lassen Sie es mich bitte über den <a href="https://gitreports.com/issue/akaessens/NoFbEventScraper">anonymen Bugtracker</a> oder auf der <a href="https://github.com/akaessens/NoFbEventScraper/issues/">GitHub Problemseite</a>.</p>
+<h3>Ist diese App kompatibel mit meinem Kalender?</h3>
+<p>Ja. Diese Anwendung verwendet anwendungsunabhängige Kalenderfunktionen, wodurch sie mit jeder Kalenderanwendung kompatibel ist. Ich empfehle jedoch den <a href="https://play.google.com/store/apps/details?id=ws.xsoh.etar">Etar Kalender</a>, da er Open Source ist. </p>

+<h3>¿Qué enlaces se pueden utilizar con esta aplicación?</h3>
+<p>Se admiten todos los subdominios de facebook, ya sean móviles (m.facebook.com) o específicos del idioma (de-de.facebook.com). El enlace debe contener un ID de evento.</p>
+<h3>¿Cómo utilizar esta aplicación?</h3>
+<ul>
+    <li><strong>Botón pegar</strong>: Basta con pegar un enlace copiado desde el portapapeles en la barra de URL.</li>
+    <li><strong>Compartir vía</strong>: La función de compartir incorporada en Android, por ejemplo, desde un navegador.</li>
+    <li><strong>Abrir con</strong>: La función integrada de Android de abrir con, por ejemplo, al hacer clic desde un servicio de mensajería.</li>
+</ul>
+<h3>¿Por qué no funciona el evento X?</h3>
+<p>Esta app se basa en la información del evento que está disponible públicamente. Si el evento no ofrece, por ejemplo, la ubicación sin necesidad de iniciar sesión, no se encontrará disponible en esta aplicación. Además, algunos eventos simplemente no proporcionan la información en un formato legible por la máquina. Los eventos con múltiples instancias son problemáticos porque no proporcionan la fecha correcta de inicio y fin cuando se extraen de m.facebook.com.</p>
+<p>Si encuentras problemas con un evento específico, por favor, házmelo saber a través de <a href="https://gitreports.com/issue/akaessens/NoFbEventScraper">bugtracker anónimo</a> o en la <a href="https://github.com/akaessens/NoFbEventScraper/issues/">página de incidentes de GitHub</a>.</p>
+<h3>¿Esta app se integra con mi aplicación de calendario?</h3>
+<p>Sí. Esta aplicación hace uso de funciones de calendario independientes de la aplicación, lo que la hace compatible con cualquier app de calendario. Sin embargo, en lo personal recomiendo <a href="https://play.google.com/store/apps/details?id=ws.xsoh.etar">Calendario de Etar</a> porque es Open Source.</p>

+<h3>What links can be used with this app?</h3>
+<p>All facebook subdomains are supported, whether mobile (m.facebook.com) or language-specific (de-de.facebook.com). The link must contain an event ID.</p>
+<h3>How to use this application?</h3>
+<ul>
+    <li><strong>Paste button</strong>: paste a copied link from the clipboard into the URL bar.</li>
+    <li><strong>Share to</strong>: Android's built-in share-function, e.g. from a browser.</li>
+    <li><strong>Open with</strong>: Android's built-in open-with-function, e.g. when clicking on a link in a messenger.</li>
+</ul>
+<h3>Why does event X not work?</h3>
+<p>This app relies on event information that is publicly available. If the event does not offer for example the location without a login, it will not be available in this application. Also, some events just do not provide the information in a machine readable format. Events with multiple instances are problematic because they do not provide the correct start and end date when scraping from m.facebook.com.</p>
+<p>If you encounter issues with a specific event, please let me know via the <a href="https://gitreports.com/issue/akaessens/NoFbEventScraper">anonymous bugtracker</a> or at the <a href="https://github.com/akaessens/NoFbEventScraper/issues/">GitHub issue page</a>.</p>

+Der Zweck dieser Anwendung ist es, Zugang zu Facebook-Veranstaltungen ohne ein Konto zu erhalten.
+Daher verwendet sie nicht die Facebook-API.
+Stattdessen öffnet sie die URI der Facebook-Veranstaltung und lädt den HTML-Code der Website herunter.
+Dieser Code sollte die Veranstaltungsinformationen in Form von strukturierten Daten enthalten.
+Die Daten werden extrahiert und zur Erstellung von Android-Terminen verwendet.
+
+Features:
+* Verwendet keine Facebook-API
+* Unterstützt "öffnen-mit" und "teilen mit".
+* Unabhängig von regionalen Subdomain-URLs von Facebook
+* Speichert den Verlauf der eingegebenen Veranstaltungen
