Setting up a recurring membership site

Is anyone using CS-Cart for a recurring membership site?

I have gone through the doc for setting up Recurring billing and I have searched the Forum but I am not “getting it”.

I can setup a Recurring Plan … not a problem. I can add Products to this Recurring Plan … not a problem. This is not actually how I would like to add Products to the Plan, but, it works.

How do I sale this Recurring Membership Plan? I add a Category: Memberships … I add two Products to Membershps: One Month and One Month Recurring.

I am lost on how to run a membership site with CS-Cart and the documentation is weak.
