Is there a better manual on Cleanfeed somewhere

I don't seem to find much when googling, but I wanted to change the stock settings Cleanfeed comes with. Is there some detailed manual or howto somewhere?
(and even if there isn't: where do the bad-files go to? is it /cleanfeed/etc? That's not quite clear, and the copy of cleanfeed I found does not have the same folder and file structure the few documents I found mention)
