 Ensure you have Docker Desktop installed, WSL2 configured, and enough free RAM to run models. 
+To configure Serge to recognize .gguf model files, modify the `values.yaml` file for Helm deployments or set the appropriate environment variables. For Docker deployments, ensure your `docker run` or `docker-compose.yml` includes volume mappings for directories containing .gguf model files.
