prince mode is not mentioned in the docs at all, see
https://github.com/magnumripper/JohnTheRipper/issues/1428
The issue also mentions a PDF document describing the attack:
https://hashcat.net/events/p14-trondheim/prince-attack.pdf

Loopback mode is only mentioned in doc/OPTIONS.

Markov mode and mask mode mode are mentioned in doc/MODES. They also
have separate doc/MARKOV and doc/MASK files.
May be all the modes should be mentioned in doc/OPTIONS as well.

Let us know if you think the docs need to be improved.
