1. Descriptions of meter types:
   The existing SE metrics guide includes this section https://helidon.io/docs/latest/se/guides/metrics#_application_specific_metrics_data which describes the meter types and shows coding examples for each.

   The MP metrics guide has a little of the same information but (IMO) in a less useful way.

   Neither the SE nor the MP non-guide metrics pages describe the meter types at all.

   Do we want to have this information in all four pages (SE and MP, guide and single page)? If not, which ones would be the best fit?

2. Summarizations:
   We could definitely mention the Prometheus format early on and link to a relevant external page.

   What other specific summarizations would help?

I like the approach that the reference (non-guide) documentation uses today, which is a table summarizing the metric types with links to the javadocs for each one. We might want to flesh out the SE javadocs as they are a little thin.

OK. I will plan at least these changes:

1. Expanding the table you mentioned to have more explanation of each meter type and add links to relevant Micrometer doc pages.
2. Including that same table in the MP reference doc page (it is not there now) with links to the relevant MicroProfile Metrics types.
3. Expanding the Javadoc for the Helidon metrics API meter type interfaces.
