I use btrfs + encryption. The tutorials just state "you have to do this and that", but not exactly what any of that means or how I apply it to my system, since the commands obviously need tinkering to make sense for my specific use case. It's not really a step by step, but a step by step jump to step X for this and then to step Y for that but make sure to do "something you don't understand / know" to be sure that "something you also don't know". It's basically all just a cryptic mess if you don't know any of it beforehand and I don't think the authors have tested their tutorials on people without prior background knowledge.
