+<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>
