### Customer feedback
#### Customer #1
"
The information in the Parameters section is in several places lacking sufficient information to be able to properly use the command. For example, "Some help" is used twice, and "The identity type" for the --identity-type option.
"
#### Customer #2
"
Note that the "--ip-rules" section only has the comment "some help." Looks like it might have been a placeholder that was overlooked.
