Q: How to configure a headless Pi Zero 2 W? A: use a temporary hotspot

[ajd4096]

I see the docs had a recent edit but it is still missing a few steps so I'm putting this here for future searchers.

The RaspAP 3.3.3 pre-built images on Pi Zero 2 W do not enable a functioning AP by default.

The simplest work-around is to create a hotspot on your phone and pre-configure the Pi to connect to your hotspot.
You can then use the phone's browser to connect to the Pi's external IP and configure the AP.

After that it all works well.
