-The LiPo Shield PCB thru-holes we will be using for the Oak are the 2-pin battery connector and the 3-pin male header for VCC/GND/VIN.  The other thru-holes (for 2-pin and 6-pin headers) are for compatibility with other Digistump development boards. **NEEDS VERIFICATION**
+The LiPo Shield PCB thru-holes we will be using for the Oak are the 2-pin JST battery connector and the 3-pin male header for VCC/GND/VIN.  The included 6-pin header is for stability only, therefore stackable headers in the corresponding thru-holes are recommended. The 6-pin headers may safely be omitted. The set of 2 thru-holes are for an optional switch or jumper (see below).

-The thru-holes for the 2-pin battery connector are slightly smaller than the others.  Notice how there are three holes for the 2-pin connector.  This allows you to mount the connector either on the bottom or the top of the PCB.  Pay careful attention to the labels on the PCB to determine which thru-holes to use for the 2-pin connecter.

-Connect the LiPo shield to the Oak's 3-pin VCC/GND/VIN female header.  Then plug in the battery to the LiPo Shield 2-pin connecter and connect the Oak's USB power to charge.  The include LiPo battery ships with some charge, but will still need to charge for about an hour.

 Your LiPo Charger Shield is complete!
-===== 0.5A Charging =====
+===== 0.5A Charging: =====
 The bottom of the LiPo Charger Shield PCB has jumper pads to enable 0.5A charging.  By default, the shield charges at 0.1A.  0.5A will charge batteries faster, however with batteries less than 500mAh such as the one included in the kit, 0.5A charging will shorten the life of the battery.  Therefore it is recommended to leave the shield at the default charging current of 0.1A for use with the included 200mAh battery.

+===== Adding a Switch =====
+Optionally, a switch or jumper (not included) may be soldered to the LiPo shield PCB via the thru-holes to the left of the 3-pin power header. When the switch is closed, power will be off.
