Do we really want to duplicate every option in the manual itself? Domen’s suggestion sounds better to me:

Issue tracker is good. I think these docs should be in autoLogin.enable description

Also, would not it be better to improve the option defaults as described in the issue?

If only one displayManager and one windowManager is enabled, I'd expect the defaults to be set to automatically. The setup above seems unnecessarily verbose.

Defaults being set automatically makes sense.

Of course auto-login is something that should be enabled manually.

Unlike a lot of other options in the manual, I'd argue that auto-login is not something many users would know about. Therefore, unlike nginx etc, users would not know to look for it if it was not easily discoverable in the manual

I think it's placement after the window manager & desktop environment section should make it very discoverable for new users.
