+Local Config Mode

+The Default Mode.
+
+Add `-mode local` or omit `-mode` to enter local config mode. In this mode, the `commander` will host the config file `config.txt` on the commander machine and `solider`s will download the config file from `http://{commander_ip}:{commander_port}/distribution_config.txt`.
+
+Remote Config Mode
+
+Add `-mode remote` to enter remote config mode. In this mode, the `soldier`s will download the config file from a remote URL (use `-config_url {url}` to set the URL).
