Since the base image is a Linux distribution, shell scripts in your workspace need to have Linux line endings when they are copied into the docker image.
 
+## Security
+
+ODTK Runtime can be started with various authentication modes including Unix domain socket ("uds"), Mutual Transport Layer Security ("mtls"), and "insecure". For demonstration purposes only, these code examples use the "insecure" mode. In a production environment, make sure that the connection is properly secured by using an appropriate authentication method.
+
 ## [Custom Environment](custom-environment)
 
 Provides the environment required to communicate with the Yum and Pip package managers in your organization. This is optional if you are directly connected to the internet. It is required if you are using a proxy/firewall or isolated network requiring different certificates, settings, or both.
