+        Owncast uses JavaScript for playing the HTTP Live Streaming (HLS) video, and its chat client. But your web browser does not seem to support JavaScript, or you have it disabled.

+      <p>
+        For the best experience, you should use a different browser with JavaScript support. If you have disabled JavaScript in your browser, you can re-enable it.
