Help to get running/setup

[Mr-S-D]

I am trying to get this to work, but I am a bit of a noob.
Could you please help me get this up and running? I have followed the description for installing hombridge and the KNX plug in. I can see everything on my iPhone. I however, I am missing this KNXD to so I can get everything to work.
Could you make an simple guide so I can get it setup up correct... something like this https://github.com/oznu/docker-homebridge/wiki/Homebridge-on-Synology#connect-ios--homekit
Dont need images just what to fill in... :)
