I have been seeing a lot about lightning node on youtube, They seem to need or are an OS in it's self, I guess I am looking for an app I can add to my device.

I have the  futurebit Apollo, I am looking to put it to better use given the mining is not profitable at all. I see umbrel and terminal web and these are full os that wont be possible with my unit. Any suggestions to put this unit to better use?
