Step by step guide to create a mapping for a new device

I have a sort of understanding what seems to be required to create lua configuration for a brand new device. In my case: Hercules DJControl Compact. After I have created the midi connection (I am using Helvium) I am able to receive events in the verbose log.

Now I would like to have some simplistic configuration example how to map a Note and a Control. I understand that midi_recv is probably where the magic happens, but it feels that to connect a completely new device I have to complete submerge myself into lua examples, instead of some "documentation". I'll try to do my best to create a new configuration for this device.
