His documentation has gotten better too! I actually just rebuilt my entire config based on his updated "standard" version. I want to use his "non-starter" config too, bc it seems remarkably powerful, but ... I need more time and brain to do that.
And, just to be clear, I rebuilt my entire config in less than an hour, copying and pasting where necessary, then it took about 20 minutes (!!) to download and setup all my software. Only one error, so I consider that a significant My NixOS Journey accomplishment! Granted, because it's NixOS, I have NO IDEA AT ALL what the error was, lol.
