This page aims to cover that (at least for using mTLS) https://webmeshproj.github.io/documentation/using-mtls/ - but you are right - administration docs in general need a lot more love.
EDIT: I've added a link to that page in the part of the insecure "Getting Started" that says "this is insecure don't do it this way". Hopefully that helps people in the right direction a bit more - but I have a long road of more documentation ahead of me.
As always - any and all contributions are welcome :)
I used to particularly enjoy getting banned from subs for being mean - with a link to my comment being a reply to someone calling me an idiot and me telling them why they are wrong.
