Hi @jiayihu. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

This is uneeded as the helm chart creates the namespace.

[jiayihu]

That is not true, at least in Helm v3. It gives error if the namespace is not created before or if you don't pass the flag --create-namespace: https://github.com/helm/helm/pull/7648

Official docs also state it: https://helm.sh/docs/faq/#automatically-creating-namespaces

[jberkhahn]

Ah, i wasn't aware that was SOP in helm3

[jberkhahn]

Could you move this down a tab, so it's included in 'helm 3 ' section?

[jiayihu]

Sure, it should be fine now although I'm not sure how the tabs thing works sorry. Also, to be quick, I edited using GH website so I hope you don't mind squashing the two commits.

[jberkhahn]

squashing the commits is fine, the tab things are for the docs website

in other news, it looks like our CI is blowing up so it might be a bit before this gets merged
