If you only want to look at (static) sites then it is enough to do the first part of
‘3 mins: Get the Peruse browser’ in the OP (you don’t have to log in with an Account Secret and Password).

If you also want to test dynamic sites, like safe://pat.ter/#/home, then you have to do all the steps before '7 mins: Get the Web Hosting Manager’.
Starting from the 7 min step, site creation is explained.
