Actually just check the example. You basically just have to setup the config.json and edit the server.js for as many bots as you wish. Parameters for the JSON like start: true make the bot start the conversation. forceStart: true will make the bot start even if waitFor is not the ID that it should be.

Also make sure that you let your bots join to your server via the Discord oAuth.

Don't forget to run npm install first to load the dependencies or you will have a very bad time. :c
