How to step by step sell squarespace templates on your own website

I'm wondering what's the step by step process to sell squarespace templates on your own site? Like what you need to do and whats a good way to make tutorials what resources do you need to send?

First, apply to become a Circle Member (you will have 6 month trial when creating a new site)

Next, create a site >> design template there

When a client purchase your template >> you duplicate the template site >> add your client as a contributor >> then transfer ownership to them.
