Dry Hop in Brew Steps

I'm not sure how to interpret the dry hop part of these follow instructions.  Do I
dry hop 5 days during the 10 day secondary, add 5 days of dry hop to secondary, or is it suggesting that I dry hop in keg??
Thanks in advance!
============ 
Fermentation instructions:
- 4 days in primary
- 10 days in secondary

dry hop and prepare for kegging...
(... dry hop 5 days)
carbinate keg with 12.54 PSI

- age beer for 30 days 

I will dry hop the last 5 days before kegging.  I do not use a secondary but I do add the dry hops after 9 or10 days in the primary then keg after 14 or so.
