Yes, that's correct. texi isn't very difficult, and we have Eli who
helps with any issues around it. There are @[cmd] markers that help
describe the text, and once you know that, you should be able to write
documentation by copy/paste. I found an "introduction to Texinfo" page,
which might be helpful giving you the basics in a short amount of time:

OK.  The patch looks good to me, except for the little formatting nits
that I already pointed out. But can you give it a few more days for
others to comment?  In particular, Doug Evans is more proficient with
the simulator than I am, I believe (which is not hard, considering
that I have barely ever touched that code).
