will be good if we add example for kubectl annotate and kubectl patch command

[black-dragon74]

The reason I did not go with that is because

• The annotation would be present on the CR already.
• User needs to just to kubectl edit and can do both the required changes simultaneously.

Lesser the commands, the better it is, WDYT?

kubectl edit is not something that can be automated easily. I prefer to give the kubectl annotate and kubectl patch commands as examples, in addition to the description you have now.
Fewer commands is nice, but you should also expect that automated tools deploy apps and configure extra things like disabling reclaim space for its PVC(s).

[Madhu-1]
