Create users in kibana basic license

Hi everyone

I would like to create different users in kibana 7.1. With different permissions in the basic license, I have read the documentation to do it, but could not understand how to do it step by step, there is a lot information and one information goes to another. I finished lost in more information that I didn't know where it went or what it was for because the guide is so technical.
I'm looking for a step by step guide to do it, something like:

first: go to elasticsearch.yml write this .....
second: run this and check this ...

You may ask for something very difficult to do or there are many ways to do it ... Does anyone know an easy guide to do it?

Thank you
