Before running, Rename config.example.yaml to config.yaml,
Then edit the config with text editor before starting bouncer.

After editing, Start the bouncer by running:
  $ ./bostr2

Or launch bostr2.exe if you're on windows.

NOTE: If there's firewall, you must configure the firewall to allow
      incomming port to the bostr2 port.
