 ### Configuration
 
 1.  Create or edit the config file in `/etc/turnserver.conf`. The relevant
     lines, with example values, are:
 
-        use-auth-secret
-        static-auth-secret=[your secret key here]

+    realm=turn.myserver.org
+    ```
 
     See `turnserver.conf` for explanations of the options. One way to generate
     the `static-auth-secret` is with `pwgen`:
