Use the rack the pot came with, put 1 cup of water in the bottom of the pot, then add the eggs (I used 14, but it can hold more- in my 8qt I do 3 dozen quite often).
Let the steam release on its own for about 6 more minutes (if it goes longer it wont hurt anything, other than your eggs eventually will turn brown if you go TOO long- they're still edible).
Put the eggs in ice and water for another 6 minutes.
The 6 minutes of cooking time will start after the pot reaches full pressure.
