I think that only the linux version is working for mining, currently.

"open config.txt, change "mining_pool=0" to "mining_pool=1", change "mining_ip=127.0.0.1" to "mining_ip=94.113.207.67",I'm running a pool on the default address of 4edadac9093d9326ee4b17f869b14f1a2534f96f9c5d7b48dc9acaed, so you can keep that there."

The slack hangout is a great way to get the latest info about Bismuth. This project is really interesting and the development is progressing rapidly.
