+This software contains four distinct modules:
+* `pool` - Which opens ports for miners to connect and processes shares
+* `api` - Used by the website to display network, pool and miners' data
+* `unlocker` - Processes block candidates and increases miners' balances when blocks are unlocked
+* `payments` - Sends out payments to miners according to their balances stored in redis
+

+By default, running the `init.js` script will start up all four modules. You can optionally have the script start
+only start a specific module by using the `-module=name` command argument, for example:

+```bash
+node init.js -module=api
