After looking at the tunnels docs I can see why the tutorials might be a little confusing. In certain areas its difficult to tell the actual tutorial steps apart from the required knowledge and examples. Its all mixed together. In my opinion, (https://whonix.org/wiki/Tunnels/Connecting_to_Tor_before_a_VPN) is the most confusing.
While I’m not fond of the Warning boxes, the information found there is vital since most users would never even think of that stuff.
