Help adding POI's to Nitrogen mixer

[Morningstar]

I have found many POI packs and singles that I just want to be included in the mixer for Nitrogen created maps. I have no idea how to do it. All i want is a19 vanilla Poi and whatever i add prefab wise.

I am not exactly adept to this at all aside from just adding mods to the mod folder

So if you know, can you give explicit step by step instructions please
