No instruction about administrator role

I see no any document described a normal server setup workflow for newbies. I want to use own server – and what set of components should I use, setup and configure? Should I use some big toys – rabbitmq, cloudron, redis? Shold I create a special admin user, give admin permisssions to a my regular user, other variant?

How can I do it? Use php bin/console fos:user:promote and set a role? What role name? I set admin and administrator, without success.

Also an important information @iav gave in the chat, is that material should be used since baggy theme is not maintained anymore
