Plunder does not use much of Urbit's terminology, outside of the linked gist, which was intended for Urbit devs, and which was cross-posted here by someone from Twitter.

I've been following along w/ Plunder for the past 10ish months out of personal interest, and I find the terminology to be about as straightforward as one can expect for a technical domain which is quite complicated.

perhaps this document is more straightforward? feedback is welcome.
