 The board itself offers a variety of features:
 * Powering the Pi using +5VSB (standby power)
-* Switching the PSU on and off using GPIO Pin 12
+* Switching the PSU on and off using GPIO pin 12
   
   The GPIO pin can be connected to PS_ON directly, or via a transistor. This is
   choosable using the three-pin jumper switch.
 
   Alternatively, the PSU can be forced to be on, by using the 2-pin PS_ON
   jumper.
+* Providing a "is the PSU on"-detection by wiring GPIO pin 11 to the 3v3 rail

 * Connecting a character LCD to the Pi
