It is a perfectly valid approach, and there are also many other perfectly valid approaches. “Better” requires a definition of what you want to be better. If there’s something that’s making you uncomfortable about the process, let us know what concern or issue you’re seeing with it and maybe we can guide you to a better way for you. But there’s nothing wrong with the way they’re doing it. Others may have different preferences (including you, YOU might have different preferences!) but they’re just preferences. It’s not right or wrong, even if some people argue that it is, they’re always going to have some preferences embedded in that judgement. There’s always more than one way to do it. That’s the joy of it, really, and sometimes you’ll have to experiment yourself to find out what ways YOU like the best, that make sense to you, that are comfortable for you, or that do things the way you want to do them.

It’s your own self-hosting setup, you get to make the choices. Sometimes the number of choices can be intimidating and lead to analysis paralysis but the only way out of that is to realize that there really is no way of finding the “best” until you’ve tried many different ways and figured out the “best” yourself. That’s why the only real advice I can give you is to just go through the tutorial you’ve found and do it the way they do it for now. You can change later, as you learn more, when not if you decide you want to do something differently. Because you will. We all do. It’s part of the process.

Not to forget: FUTO is evil.
