[jat-canonical]

This commit adds the instructions to make use of the newly added support for instance profiles in AAR.

LGTM, can you though add a link to the release notes for 1.21 so we can get that linked for people interested?

[keirthana]

Some minor suggestions and I see that Simon has already suggested adding the link to RN

[keirthana]

LGTM

@morphis Are you fine with the current changes? Can I go ahead and merge+publish this update?

[morphis]

@keirthana if we get a link into 1.21 release notes, then I am fine. However that seems to be still missing from the PR.

[jat-canonical]

@morphis They have been added here. Let me know if it needs changes.

[keirthana]

@morphis I think there is some confusion here about whether you want the link from the doc to the RN or the reverse. In your most latest comment, you say "into the RN" , so I think it is the way we usually do - from the RN to the docs. Correct?

[jat-canonical]

@morphis could you confirm ?

We need to link from the RN to the docs.

Since the pending comment has been addressed, I am merging and publishing this PR.
