Customize Pro Site Checkout Page

Hi there!

I'm setting up this plugin for a client who requested it and am wondering if I am missing a step to customize the checkout page? Currently, I have two levels (Lite and Premium) set up and when I go in (as a user) to upgrade my site - the checkout page displays the name of the level and the price - - but no description?

Is there a way to display a list of options available with each level? Otherwise, users really have no clear idea what features each level provides in order to make a decision on which package to upgrade to.

Screenshot of my checkout page is here: http://awesomescreenshot.com/0abrlz571
A list of features that go with each level is needed here.

Without the ability to provide at least a simple description, it's a confusing user experience. I'm sure I'm missing something ... short codes ... anything?

Many thanks!
