Cloud Hetzner and Docker with NodeJS

I have read George’s ratings and in general on the web for Hetzner’s offers, and then I have registered an account on Hetzner and now I’m trying to figure out how I should set up a Cloud Server with Nodejs (choosing one of the offered solutions)
Unfortunately, however, I must admit my ignorance on the subject, and I must say that I was confused about how to proceed. A very different situation from the various Hosting and VPS so far contacted.
Does anyone know if there is a step by step tutorial to perfectly configure a Cloud on Hetzner (Ubuntu / Helsinki) up to a control panel?
I’ve already started over three times but I wouldn’t want to mess it up
