I'm LGTM on this. And happy to just merge it as it is. (Thank you so much for doing it @chadmcrowell 🙏)

But I'm actually not aware of the process myself. So, will let someone expert review it once if possible

@pnbrown, @chris-short - could you please review the content. Thank you!

[Priyankasaggu11929]

also cc: @kubernetes/sig-contributor-experience-leads if anyone else have context and can review and help merge. Thanks!
