First of all, thank you for following me! No, I haven't written anything about how I set up my BTCPay store, but if you want to sell your paintings, I recommend using the Plebeian Market platform. Here you can see my gallery:

Original oil paintings

It is much simpler and more intuitive than creating a website and connecting a BTCPay server for sales. In addition, the Plebeian developers will soon update the site with many interesting new features.
