   - `port` the port which the server will listen
   - `advertise` should this server be advertised on the Master Server?
   - `addonsfolder` the location of your addons folder. **omochao** will load all your files in alphabetical order. if you need to load files in different order, put them under some folders so that they're loaded in a certain order (i have three folders, `a_first`, `main`, `z_last`)

+  - `showMapChange` if true, prints a message whenever a new map is loaded

   - `token` app token goes here. if you've followed the guide I left in the *how-to* section, put here the token you copied on step 1
   - `channelIds` **omochao** will write to and read from these channels
