+### TURN servers
+
+The server can be configured in order to communicate to clients through a TURN server. The server must be set in the configuration file:
+
+```yml
+webrtcICEServers: [turn:user:pass:host:ip]
+```
+
+Where `user` and `pass` are the username and password of the server.
+
+If the server uses a secret-based authentication (for instance, coturn with the `use-auth-secret` option), it must be configured in this way:
+
+```yml
+webrtcICEServers: [turn:AUTH_SECRET:secret:host:ip]
+```
+
+where `secret` is the secret of the TURN server. rtsp_simple_server will generate a set of credentials by using the secret, and credentials will be sent to clients before the WebRTC connection begins.
