How to integrate Denon AVR-X4400H AV Receiver to ST?

How to integrate Denon AVR-X4400H AV Receiver to ST? I see a depreciated thread, but has a new one been released?

Obsolete or deprecated doesnt mean much on this forum, other than if you have issues, you’ll need to fix it yourself. This DTH still works for HEOS receivers until it stops working.

This is awesome. Just what I wanted.
I am very new to SmartThings, this is my 3rd day with it. And github based integration is literally much ahead of my current learning curve with ST.
Is there a tutorial I can use that show how to integrate Github based import into ST api?
