+=== CoherenceJob CRD Support
+
+By default, the Operator will install both CRDs, `Coherence` and `CoherenceJob`.
+If support for `CoherenceJob` is not required then it can be excluded from being installed setting the
+Operator command line parameter `--install-job-crd` to `false`.
+
+When installing with Helm, the `allowCoherenceJobs` value can be set to `false` to disable support for `CoherenceJob`
+resources (the default value is `true`).
+
+[source,bash]
