I ripped off @remcoros page: https://lnpay.me/
- add point of sale app, product list style, add each "button" as a product
- btcpay > server settings > policies > customization (Display app on website root) 

 what did you use to expose on clearnet? 

 Vps + tailscale 

 + caddy (to handle the certs and proxy more easily). I'm still being extra lazy about creating a package for @Start9 

 cool!
