Thanks a lot!

Maybe this should be merged to the paragraph above, so that the relevant configuration can also be added to the example snippet? That would make it easier for users to copy both options at once to update their ConfigMap.

Agree with @qmonnet , I think it's pretty important for getting started guides to have a ready-to-copy snippets.

[manuelbuil]

Thanks for the change, looks all good to me now :)

Conformance test failures seem related to cilium/cilium-sysdump#100. The generate-api test failed because quay.io is currently down.
