Hi Orrin,

You can find here the complete online manual: http://j.mp/tapr-qrpi

Heat sink is completely unnecessary (my personal opinion) on RPi's if you
don't do any modification (CPU and MEM frequency tunining) and you keep
your RPi  within the specified operation temperature range.
Of course if it's not an "obstacle" then it's a good idea to add some more
"heat margin".
