+    <p>
+      GameMode is a daemon/lib combo for Linux that allows games to request a set of optimisations be temporarily applied to the host OS and/or a game process.
+    </p>
+    <p>
+      It was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave or ondemand governors, but is now host to a range of optimisation features and configurations.
+    </p>
+    <p>Currently GameMode includes support for optimisations including:</p>
+    <ul>
+      <li>CPU governor</li>
+      <li>I/O priority</li>
+      <li>Process niceness</li>
+      <li>Kernel scheduler (SCHED_ISO)</li>
+      <li>Screensaver inhibiting</li>
+      <li>GPU performance mode (NVIDIA and AMD)</li>
+      <li>GPU overclocking (NVIDIA)</li>
+      <li>Custom scripts</li>
+    </ul>
