SmartThings MQTT Bridge - config.yaml problem

I installed the SmartThings MQTT Bridge as described in the BurnsHA YouTube video. No problems, except my /opt/mqtt-bridge folder is empty. The instructions call for editing the config.yaml file (at 07:35 in the video), but in my install, it doesn’t exist. Does anyone know what is wrong here or how to troubleshoot/fix it? Thanks in advance!

I looked back at my notes when I did this several months ago…
that file does not exist. You have to create it.

Thanks for the reply! I tinkered around and actually got all of my SmartThings devices working directly with HA and my HUSBZB-1. The only thing left to migrate over is my Arlo camera system, which is another problem entirely.
