+    <p>
+      Glide is a simple and minimalistic media player relying on GStreamer for the multimedia support
+      and GTK+ for the user interface. Glide should be able to play any multimedia format supported by
+      GStreamer, locally or remotely hosted. Glide is developed in Rust.
+    </p>
+    <p>
+      Once Glide is running you can use some menus to switch the subtitle and audio
+      tracks, play, pause, seek and switch the window to fullscreen. There are
+      also some keyboard shortcuts for these actions:
+      <ul>
+        <li>play/pause: space</li>
+        <li>seek forward: meta-right or alt-left</li>
+        <li>seek backward: meta-left or alt-right</li>
+        <li>switch to fullscreen: meta-f or alt-f</li>
+        <li>exit from fullscreen: escape</li>
+        <li>quit the application: meta-q or ctrl-q</li>
+        <li>load a subtitle file: meta-s or alt-s</li>
+        <li>increase volume: meta-up or alt-up</li>
+        <li>decrease volume: meta-up or alt-down</li>
+        <li>mute the audio track: meta-m or alt-m</li>
+        <li>open a new file: meta-o or alt-o</li>
+      </ul>
