 ### Use
 
-Run one or multiple rcon proxies by setting an environment variable `Q3RCON_PROXY`
+Run one or multiple rcon proxies by setting an environment variable `Q3RCON_TARGET_PORTS`
 
 for example:
 
 ```bash
-export Q3RCON_PROXY="20000:28960;20001:28961;20002:28962"
+export Q3RCON_TARGET_PORTS="20000:28960;20001:28961;20002:28962"
 ```
 
 This would configure q3rcon-proxy to run 3 proxy servers listening on ports `20000`, `20001` and `20002` that redirect rcon requests to game servers on ports `28960`, `28961` and `28962` respectively.
