 <h2>Configuration for Live Mining</h2>
+<p>Live Mining must also be enabled on the options page, not just configured.</p>
+
 <p>Live Mining requires <a href="https://apps.ankiweb.net/">Anki</a> and the <a href="https://ankiweb.net/shared/info/2055492159">Ankiconnect</a> plugin.</p>
 
 <p>If Live Mining is enabled, then when you mine notes to the mining storage, Nazeka will also attempt to connect to Ankiconnect and tell it to insert a new note.</p>
