+#### Rust Rcon Support
+
+To make this library work with rust, please ensure that you start the server with ` "+rcon.web 0"` to enable legcy mode.
+
+It's also worth noting that Facepunch will eventually [remove](https://github.com/Facepunch/webrcon) legacy mode (source protocol implementation) sometime in the future and will be replaced by their websockets implementation as the default.
+
+Currently, there are no plans to support the web sockets version.
