openWakeWord -> Synology Container Manager

Hello there, I´ve bought a AtomEcho and tried to install openWakeWord within the Container Manager on my Synology where my HomeAssistant is running. I got the Image but to be honest I have no Idea what to do, which steps are necessary to get it working…
Does someone point out a good tutorial for that?
I do not know anything about Docker and Dockercompose…

thanks
