Section Number and Name:
2. Create a Backup CR, as in the following example:

Describe the issue:
Explanation notes 3 and 4 are duplicate

apiVersion: velero.io/v1
kind: Backup
metadata:
name: <backup>
labels:
velero.io/storage-location: default
namespace: openshift-adp
spec:
hooks: {}
includedNamespaces:

• <namespace> (1)
  includedResources: [] (2)
  excludedResources: [] (3)
  storageLocation: <velero-sample-1> (4)
  ttl: 720h0m0s
  labelSelector: (3) <-------- 3 was already used above
• matchLabels:
  app=<label_1>
• matchLabels:
  app=<label_2>
• matchLabels:
  app=<label_3>
  orlabelSelectors: (4) <------- 4 was already used above
• matchLabels:
  app=<label_1>
• matchLabels:
  app=<label_2>
• matchLabels:
  app=<label_3>

And as a consequence the explanations for labelSelector and orlabelSelectors are missing.

Suggestions for improvement:
Go from 1 to 6 and add explanation for labelSelector and orlabelSelectors
