Yes I’m on it and will update the documentation shortly. Making the theme work with cart66 is quite simple though.
Try it out with one product. As soon as you’ve created one you can select it in the dropdown on the posts you created for the menucard. This way you can link the menucard posts to the cart66 products. It’s as simple as that. If I’m not mistaken then the cart66 pages should be added automaticly when you install the cart66 plugin.
Hope this helps 🙂
