Stjohnjohnson smartthings mqtt bridge

Has anyone used the stjohnjohnson/smartthings-mqtt-bridge, as i would like to use it on my RP4 using docker and install node red, mqtt bridge and eclipse-mosquitto broker to it, and connect to my smarthings hub through the bridge, I just need help know this works and with the config file, so I'm sure I'm doing the right thing, as I'm very new to this. all help much appreciated.

I'm using it but I don't have it loaded in docker and it sits on my x86-64 machine with Mosquitto, node-red, scripts and such.
