How to write all fundamental information for customers about subscribing our Kafka topic

Hi all,

I am writing documentation for our customers and I want to be sure that it is very good and helpful.

We just rolled out a feature that upon various events publishes messages on an Eventbus, under our specific topic.

What kind of information would you like to read in a similar page, what would positively impress you?

My idea would be to put there a brief introduction on Kafka, the full event list and an example of the Json data, is there anything else I should add?

Thanks for your help and suggestions.
