The command reference described wx as ZIP-only and gwx as a list of fields. It now gives both commands' accepted locations, options (tomorrow, hourly, Nd, alerts), the order they fall back through when no location is given, the unit settings, when the reply names the place, what custom WXSIM and MQTT sources answer, and that both work in scheduled messages. The config example's default_state/default_country comments say how they affect the place name, the no-location comment lists default_city, and the weather service page lists the wind units that actually exist.
