1. Download the latest server files (currently, that would be this: http://mirror.technicpack.net/Technic/servers/bteam/BTeam_Server_v1.0.6.zip).
2. Extract them to a folder where you'll host the server files
3. Modify the launch.bat, if you care to and know what you're doing
4. Run 'launch.bat' and your server should be up and available on your LAN (by default on port 25565)
5. If you want to make it available to people outside your LAN you're going to have to configure port forwarding
If you want to run the server on the same computer on which you're playing you'll need a comfortable amount of RAM. 8GB works for me, but we only typically have 3-5 people on our little server and I run about 1.5GB to 2GB for both the game and the server.
Server GB is set in the launch.bat file (note the min [-Xms] and max [-Xmx] values)
