Sorry I took a while to reply.
The Software Overview page only explains how to continue using the Kerlink gateway, where as we have created a gateway using a raspberry pi.
Edit: Plus, not only that, but I can't access the link at:
"Install Demo LoRa Packet forwarder as described Here."
I don't have a login, and there doesn't seem to be a way to create one.
Seems to be one of many issues with the online documentation...
