DGTeam Firmware Documentation

[#1]

Sorry if this is in the wrong section. It comes between hardware and software so I didn't know quite where to post it. 
I've been searching for documentation for the DGTeam firmware and have failed to find any.
Does anyone know where I might find some? Thanks.

I've just checked that site again in case I'd missed something.
As far as I can see there is a list of the main features and a Firmware Upgrade Tutorial.
I was actually seeking a 'how to' guide on the listed features. Does one exist?

There used to be a forum where features etc. were discussed, but since DGTeam went into "hibernation" that is not accessible.
So I think it's just WYSIWYG.

In the last few weeks the firmware downloads have also become inaccessible
