Custom Purchase Order Template Documentation?

I'm looking for a breakdown of the `Order` model used in this custom template:
https://github.com/merchantos/PrintTemplates/blob/master/purchase_order/purchase_order.tpl
I'm trying to access custom fields on the purchase order and can't find any documentation.
Thanks!

The values shown in a Purchase Order are served from our Order endpoint.

A purchase order template is a combination of HTML, CSS, Javascript and Twig
