One might be tempted to say that this method requires a lot of insight. And it does require some, but not a lot. This is very doable for most people.

You need to learn a bit about git, but that's about it. The DNS parts are mostly about knowing what you need to do (add an A-record and/or a CNAME) and then it really depends on your DNS service provider or registrar. Some registrars manage to make a mess of it. I use a registrar that has an extremely bare bones interface that is exquisitely clear.

Having tried to help various friends who use all-in-one hosting solutions, I would have to say that it is far, far easier to spend a couple of hours learning just enough DNS and Git + Github to get this done than use those systems.

Because if you use the method outlined in the above mentioned website, you will have tons of documentation and community support to lean on.

Most all-in-one-solutions end up being between you and a useless service provider who will lose money on you if they provide you with any support.
