Chef automate 2.x tutorial needed

I need to be able to use Chef automate 2.x I am not able to find a tutorial for Chef automate 2.x.
This tutorial looks like it is for Chef automate 1.8:
https://learn.chef.io/modules/manage-a-node-chef-automate/windows/automate/set-up-your-chef-server#/
as it uses still automate-ctl instead of chef-automate like chef automate 2.x does.
within chef-automate i can't find a way to establish the Connection from chef automate to chef infra Server. chef-automate does not have setup command any more. How the connection from chef automate to chef infra server is done now?

Hey @TvG71!

Welcome to the Chef Discourse board. Can you take a look at this documentation and see if it suits your needs? https://automate.chef.io/docs/install/

It should have all the context needed to get you on your way.

Of course if you have any issues, please let us know.

Thank you!
