How do I create a page and set the Membership Level?

Eventually I get somewhere. But when I am trying to get started, I often spin my wheels and sit idle. True now for MEMBERSHIP plugin. I have set up 5 levels on my site ( but cannot find out how to assign a Membership LEVEL to that page. Can somebody help with a clue to help me make the simple first step?
