 ## How to access
 
 If you want to see what the exporter returns, you can access :
  
- `http://<ip>:9591/metrics?ip=<srcds ip>&port=<srcds port>&password=<rcon password>`
+ `http://<ip>:9591/metrics?ip=<srcds ip>&port=<srcds port>&password=<rcon password>&game=<game>`
  
 ## Grafana dashboard
 
 Is there a Grafana dashboard available ? Of course!
