Drying CFB

For the first time I've grown  a CFB called Coco blanc á rames.  They say the beans can be dried, which I assume means leave them on the vine to ripen and go crispy and bring under cover.   I don't have much experience using dried beans so can you tell me whether when using should I follow the usual precautions to boil for 30 mins, like kidney beans, then use in whatever recipe?
