In reading the [Getting Started](http://docs.particular.net/nservicebus/persistence/) doc for NServiceBus I see that it can (and should) use a Database for subscription information when scaling out to more than one machine.

But it does not say how. I have looked at the other docs I don't see how to do this (though I admit I have not read them all yet).

Can anyone point me to where I can find this info? Or tell me how to do it?
