-		The three buttons go directly in the small pockets on the bottom part of the printed case. While the front pins are put into the small holes in order to fasten them tightly, the pins on the other end should be bent up into a horizontal position. We can easily solder them to jumper cables there and connect to the Raspberry Pi. Connect the buttons to pins 9 (for PREV), 10 (for PLAY/PAUSE) and 11 (for NEXT). The other sides go to the ground pins 20, 30 and 34.
+		The three buttons go directly in the small pockets on the bottom part of the printed case. While the front pins are put into the small holes in order to fasten them tightly, the pins on the other end should be bent up. I ended up soldering some F-M wires directly onto the pins, but using F-F wires is also an option. Connect the buttons to pins 9 (for PREV), 10 (for PLAY/PAUSE) and 11 (for NEXT). The other sides go to the ground pins 20, 30 and 34.
