In the section 4.23 - Step 4, the example doesn't work.

There is a format error in the example below:
~~~
spec:
..
env:

• name: ARTEMIS_EXTRA_LIBS
  value: '/amq/init/config/extra-libs'
  resourceTemplates:
• selector:
  kind: StatefulSet
  patch:
  kind: StatefulSet
  spec:
  template:
  spec:
  initContainers:
• name: jdbc-driver-init
  image: <custom container image with JAR>
  volumeMounts:
• name: amq-cfg-dir
  mountPath: /amq/init/config
  command:
• "bash"
• "-c"
• "mkdir -p /amq/init/config/extra-libs && cp <_JAR file> /amq/init/config/extra-libs
  ~~~

"spec.resourceTemplates.spec" is not exist. The correct one should be "spec.resourceTemplates.patch.spec".

The same issue can be seen in the step 5.
