Well... in the event dir, there's a nip but then in the kinds folder there's also a nip and other directories. idk maybe I just haven't looked through thoroughly enough but I guess that's what I'm getting at is deciphering the flow for adding thingd to the NDK is not straight forward.

Fair. There are some nips that define new kinds (usually on the kinds sub dir) and there are other nips that define behavior or events etc.
It definitely assumes quite a lot of knowledge of the nips.
