Allo Digione Signature Setup - I haven’t got a clue

Is there anyone in the Wolverhampton or West Midlands of the UK, who could help me set up the streamer? I have just bought it from Allo and want to use the wireless feature to stream to my DAC, but it’s way beyond my IT skills.
Appreciate any help you can give me.
The streamer is a Raspberry Pi 4.
Also the image on the website doesn’t seem to work??? Of course it could be me lol
