Ok what do you have to do to customize the Pro Sites Checkout Page? I see 1000 forums with different bits of code, broken links and hooks from 3 to 4 years ago but nothing solid on what to do. It seems silly to have this whole plugin resolve at an ugly checkout page.
I have a customized theme running Pro Sites on a multisite install. If I wanted to make changes to the layout and style of the checkout page what do I have to do? What do I add to functions, css etc etc.
Honestly a video would be nice. It seems like people just want to know what to do. Everybody in here codes so a nuts and bolts would be awesome.
