Pro Sites - Getting Started

I am trying to use Pro Sites and while I have used WP for many years I am new to the idea of a multi site network. I am really excited to get started. I made theme templates to sell using new blog templates, set up SSL, white labeled the back end office of all my themes - and I have a bunch of great ideas :slight_smile: I am a little lost on setting up Pro Sites. I am wondering if there is any further documentation or video tutorials? Basic questions I have right now would be... where are the pricing tables? I dont see a code anywhere to generate them, I would think I only need this set up on my main website but I see it has to be network activated. Thanks for any advice on helping me get started!
