The only thing that needs to be corrected on this doc, is when you create the new "Administrative username", do not use 'admin', use something else like cisco/cisco and then after the box reboots, go in and change the admin username with the 'username' cli command.
When you change the password in the cli, do not forget to put 'superuser' on the end of the command or you will have to do the same procedure all over again.
