Where can I find documentation on YATE?

Question

SIP

Good afternoon.
I'm trying to understand yate. While I'm reading docs.yate.ro/wiki/Yate_as_SIP_server, but there is catastrophically little information. The joke about the fact that "there is a lot of documentation on yate, but it's all in c ++" can not be joked, I already know it)
It's enough to set up the simplest routing, but I would like more details. Maybe someone has their own experience with comments that it is not a pity to share with the public.
