+### Wildcard Domain Support
+If the MiniConnect server supports wildcard domains, you can use the ViaProxy wildcard syntax to pre-fill the server address and version.\
+Examples:\
+- Format 1:\
+  `address_port_version.viaproxy.hostname` e.g. `server.example.com_25565_1.8.viaproxy.example.com`\
+- Format 2:\
+  `address.<address>.port.<port>.version.<version>.f2.viaproxy.hostname` e.g. `address.server.example.com.port.25565.version.1.8.f2.viaproxy.example.com`
+
+Both fill `server.example.com:25565` as the server address and `1.8` as the protocol version.
