+      A very WIP custom discord client that supports streaming with audio on
+      Linux, made possible by the
+      <a href="https://github.com/edisionnano/Screenshare-with-audio-on-Discord-with-Linux" >
+        great work
+      </a>
+      of <a href="https://github.com/edisionnano">@edisionnano</a> and the
+      <a href="https://github.com/Soundux/rohrkabel">Rohrkabel</a> library by
+      <a href="https://github.com/Curve">@Curve</a>.
+    </p>
+    <p>
+      The purpose of this project is
+      <b>not</b>
+      to provide an alternative to the original Discord client. Rather, it
+      should be used in addition to the original client in case you want to
+      stream something, maybe used with a second account. For anything else,
+      this client has way too many things that work less well than in the
+      original client.
