+# MultiMC builder setup
+
+This describes how to set up MultiMC teamcity build agents so they aren't annoying.
+
+1. Copy `env.example` to `.env`
+2. Bring up all the machines with `docker-compose up` and observe the auth tokens they get from TC
+3. Bring all the build agents down
+4. Fill in the real auth token into `.env`
+5. Bring the agents up, remove all dead ones from TC, authorize the running ones
