This has a nice visual guide that requires you to know how to buy a raspberry pi, how to plug in a raspberry p, how to plug in an sd card (twice), and how to navigate to a url.
This is the problem with lots of stuff similar to HA when it tries to break into a non-enthusiast audience: people don't WANT to choose how to install it. Most of the time they have no clue why they would choose one thing over another and giving them those choices is confusing and overwhelming.
It's like starting a an intro to Nix tutorial with by asking if the user wants to enable flakes.
I say this as a very active user of HA & Nix for 5+ years.
I've had HA for +4-5 years too.
