A good example of what exactly? Because regarding (a), this is just a quick reference for options. Nothing more, nothing less. As for (b), you're literally looking at detailed documentation. It's almost as if you made up your mind before opening the link.

If nix/home-manager documentation wasnt awful this site wouldn't be needed. And the level of detail should be way better than a one line sentence with no examples.

There's nothing in this site that's not in the official Home Manager documentation. See here:

https://nix-community.github.io/home-manager/options.xhtml

Or alternatively:

    man home-configuration.nix

The official documentation does have examples.
