Ipsilon documentation

Hey folks! I would like to ask you about Ipsilon and its documentation. I have made the last significant commits to it over the past few years (mostly during the AAA project development), and I might be one of the few people who *kinda* know how it works. At least some parts. That's not a very good bus factor and I could write some documentation, since it's pretty important in our authentication system. Ipsilon does have documentation here : https://ipsilon-project.org/doc/intro.html (and a bit here: https://pagure.io/ipsilon/). To prioritize what I'll write, I wanted to ask you what you would like to see in Ipsilon's documentation that is missing today. Could you check out the existing doc and let me know? Thanks! Aurélien
