Stream Deck plus set up

I'm sure this is an issue of my understanding. I am trying to set up a stream deck plus to use with my Nomad on a PC. I have installed the companion app, the stream deck app and downloaded the config file. I have read the instructions that I can find online. In the companion app I can see the buttons that would or should work in EOS. However, I can't seem to get them into the stream deck itself. 

I need some basic instruction as I'm not great with source code.

Thanks
