+### Standalone Instance, kerberos
+In this configuration, the user will need to provide certificates and the
associated configuration information. Optionally,
+if the kerberos provider of interest is operating in kerberos modes,
certificates will additionally be needed.
+Of particular note, is the `AUTH` environment variable which is set to
`kerberos`. Additionally, the user must provide a
+username as provided by the configured kerberos server in the
`INITIAL_ADMIN_IDENTITY` environment variable. This value will be
+used to seed the instance with an initial user with administrative
privileges. Finally, this command makes use of a
+volume to provide certificates on the host system to the container
instance.
+
+#### For a minimal, connection to an kerberos server using SIMPLE
authentication:
+
+ docker run --name nifi \
+ -v /User/dreynolds/certs/localhost:/opt/certs \
+ -v /home/kerberos:/opt/kerberos
+ -p 8443:8443 \
+ -e AUTH=tls \
