@charlotte-hoblik as you have a ticket related to using these steps, you'd be an ideal reviewer for this PR :)

[leemthompo]

thanks for all the comments @lcawl, I can refactor this into more comprehensive coverage and we can decide whether it makes sense to cram it all into the quickstart or add more overview information elsewhere in these guidelines for Kibana (i.e. a sibling to https://www.elastic.co/docs/contribute-docs/api-docs/overview#example-elasticsearch)

(Putting this back in draft for time being)

Neat addition. I just got to test these instructions for Kibana and besides a few small things, this worked out well. Thanks for putting it together

@leemthompo 💅
