EDIT: Practices and Guide/Tutorial on how to enable them e2e from Go client, through Prometheus to querying

I would imagine we should update https://prometheus.io/docs/practices/histograms/ for native histograms, and then add a Guide or a Tutorial with the hands-on help. (What's actually the difference between Guides and Tutorials on prometheus.io?)

But first of all, I have to write a proper spec (or a candidate spec) in the Concepts section.

A blog post is maybe the wrong format (beyond an "announcements and highlights" thing).

Nice, Guide/Tutorial and Practices sounds good! Changing the title.

No idea what's the Guide vs Tutorial. To me it feels Guides are general rough steps you should do, whereas Tutorial feel like reproducible scenario you could walk in with more detailed commands (?)

Hey @bwplotka , if this issue is not being worked on , can you assign this to me?

Note that there is #2868 under review right now.

Let's get this in first and then find out what is still needed.

I would also like to note that a good guide/tutorial will need deep understanding of native histograms. Using a gen-AI tool to produce such a guide/tutorial without being able to review and edit the result based on deep understanding will be counterproductive. It will cause more review work for a qualified reviewer than writing it themself.

(Besides, any user can ask gen-AI to explain native histograms to them. An AI-generated guide/tutorial will by definition not be better than that.)
