+title: Container CLI
+description: Configure and manage your Nestri Relay environment using CLI parameters for WebRTC settings, STUN servers, local IP handling, and TLS options.
+icon: 'lucide:terminal'
+---
+
+The Nestri Relay CLI provides configuration parameters to manage your relay environment. These options allow you to set values like `WebRTC ports`, `STUN servers`, and `TLS certificates`. Additionally, you can enable `verbose` mode and debugging for troubleshooting purposes. This documentation details each parameter to help you optimize your relay setup effectively.
