The bootstrap is a support net for self-driven people in Switzerland.
To learn more about it, visit http://thebootstrap.ch/.
You can also read my long-winded post on the thought process behind it: Hi, the world is yours!
Not much so far. Since it's open-source software, you could just roll out your own instance.
However, I'd rather work directly with you and set you up with a subdomain for your own community: this way we don't get too fragmented.
Remember that the bootstrap exists to serve existing real-life communities, not to create online communities out of thin air.
Read INSTALL.md, it should get you started quickly.
