QA for documentation

[brucellino]

@EliciaHeera this is to ensure that you understand how to use the role and whether the documentation is understandable.

The README.md should suffice entirely to tell anyone using the role how to use it in an arbitrary environment. If you can't use it, please respond to the ticket with a single issue per response.

E.g :

• how do I apply the role ?
• how can I test it in a testing environment ?

etc.
