The FAQ was originally written in 2015 and somethings have changed since then. But posts in the forum (unlike the community – created wiki) age out after a while and then you can’t edit them anymore.
If you read all the way through that thread, you will see that in post 27, the instructions for step five were updated. That would probably have cleared up the confusion.
I know that’s annoying, but it happens in some of the older FAQs.
