+<h1>QCPUFreq Help</h1>
+
+This application allows you to adjust your maximum CPU speed.
+<br><br>
+This enables you to overclock your CPU easily, but of course you can also underclock the CPU if desired. Underclocking might save some battery power if you are running applications like emulators, which cause your CPU to always run at full speed when it is really not required. Please note that lowering the maximum CPU frequency does not always save battery power and is not always the best choice!
