Shortcode Documentation and [shoppingcart] shortode

Hi Shopify,

The plugin will create multiple pages with extra shortcodes, [userlog], [shoppingcart] and [transactionresults]. Those don’t seem to do anything.

Could you explain the purpose of those shortcodes and if those are actually supposed to do anything?

Where could I find the Shortcode documentation?

Thank you and well done for creating a great plugin.
