As far as I know the SimpleX team adds their servers to the preconfigured list of servers in the app.
So if you host SMP servers for others, you could share their QR code (along with a quick description) in some forum or your own website (I know a hoster of serval private services who also maintains SMP nodes).
Whats the easiest way to contribute to the simplex communication network? When I run a relay node, how do I notify the network that my instance exists
