Admin users simply go into the Add-Ons tab.  Click on website button, and in here you'll see the instructions.  

A supplier also has the option of setting up 'Store Locator' which you'll see on this same page.  Where a Supplier has a network, you can list these in here.  This means when your customer comes through your website they will be presented with your locations to select from.  We will then tell you which location your customer wants to trade with.
