This project is very confusing to me.
They to offer open source code. But the repository is a vagrant box with the code pre-installed. I don’t see an actual client and their documentation suggests that most people use them as a centralized service.
Also they say nonprofit at the top and at the bottom of the page say not-for-profit which are entirely different.
I was considering adding them at one point but they don’t make it easy to use their network without using their centralized service.
