+
+        <main>
+            <h2>Was ist das hier?</h2>
+            <p>
+                Diese Webseite zeigt den Fahrplan der <a href="https://ilztalbahn.eu">Ilztalbahn</a> an,
+                und macht sonst nicht viel. Bitte beachtet, dass diese Seite nicht von der Ilztalbahn GmbH,
+                dem Förderverein o.ä. betrieben wird, sondern nur ein privates Projekt einer einzelnen Person
+                ohne jede Verfügbarkeitsgarantie ist.
+            </p>
+
+            <h2>Wie funktioniert das?</h2>
+            <p>
+                Die Ilztalbahn bietet ihren Fahrplan im offenen Standard <a href="https://gtfs.org/">GTFS</a>
+                an. Weil GTFS an einigen Stellen ein manchmal schwer zu benutzender Standard ist (und nicht
+                jeder Besuch dieser Webseite einen Aufruf des GTFS der Ilztalbahn triggern muss), hängt noch
+                ein kleiner Server dazwischen der die relevanten Teile in JSON übersetzt.
+            </p>
+            <p>
+                Der Fahrplan ist jeweils für einen ganzen Sommer gültig, und wird auch währenddessen
+                (soweit ich sehen kann) nicht verändert oder aktualisiert — es gibt also keinerlei Garantie,
+                dass die Daten hier korrekt sind!
+            </p>
+
+            <h2>Gibt es das auch als App?</h2>
+            <p>
+                Aktuell nicht. Wenn ihr die Webseite im Browser offen lasst, sollte sie sich aber auch offline
+                noch automatisch aktualisieren.
+            </p>
+
+            <h2>Werden Verspätungen/etc. angezeigt?</h2>
+            <p>
+                Leider nein. Es gibt für einige Fahrten der Ilztalbahn zwar Echtzeitdaten von der DB, diese
+                sind aber nicht im Datensatz der Ilztalbahn enthalten. Vielleicht kommen die hier noch
+                irgendwann mit rein, solange könnt ihr sie (falls es sie gibt) bei
+                <a href="https://marudor.de/Passau%20Hbf">marudor.de</a> anschauen.
+            </p>
+
+            <h2>Gibts hier Quellcode zu?</h2>
+            <p>
+                Ja klar, hier: <a href="https://stuebinm.eu/git/woitb">git-Repository</a>
+            </p>
+
+            <h2>Datenschutz?</h2>
+            <p>
+                Diese Seite läuft aktuell auf einer kleinen vps bei <a href="https://hetzner.de">Hetzner</a>,
+                geloggt werden aktuell nur Zugriffe, aber keine IP-Adressen.
+            </p>
+
+            <h2>Wer macht das hier?</h2>
+            <p>
+                Auch nur so ein Mensch im Internet. Falls ihr wollt könnt ihr
+                <a href="https://pleroma.stuebinm.eu/stuebinm">auf meinem Pleroma</a> vorbeischauen.
