+### Generating Configuration
 
-The default GraphQL RPC configuration is provided in the `examples` directory of the Sui repo.
+You can run the GraphQL RPC server without a configuration file, which will use default values. To customize settings, generate a config file using the command below and edit it as needed:
 
-<ImportContent source="/examples/prod-config/graphql.toml" mode="code" />
