Yes, the docs for this kind of thing are usually missing and it's up to the developer to sort out the specifics. this is something we hope to address in the new versions, but for now we're stuck with it.
However, it's a long time since I looked at this, but basically you need to create a setting called "calcship.provider".
I think, in this you need to place your shipping class and assembly. e.g.
"NEvoWeb.Modules.NB_Store.CalcShipInterface,NEvoweb.DNN.Modules.NB_Store.ShipExample"
This should then use your shipping provider rather than the in-built calc.
But you'll need to have the knowledge to be able to create and test the shipping provider you've added.
