Official thread of the coin on this forum. Rig providers should be experienced enough to know what has to be done from there on. The whole point of this service is that customers don't have to take care of technicalities regarding rig setups to mine certain coin (the only technicality is setting rig to point to your pool).
If there is new coin (coming) out with special algo, just create order and write in comment coin name. This is a method to "inform" providers that you need rig for that coin. Sooner or later someone might put a rig up to fit your needs and fill your order.
