First of all you should understand the structure and mechanics of express and the library before you use them together. This readme provides enough code examples, you just put it together to bot.js file and run 'node bot.js' in your terminal. It's also work on local and remote machines (except network firewall issues).
The library you sent before provides folder 'examples' for quick start, however it's the worst thing to build a library on another fat library that was built on another fat ones just to provide the example folder for dummy start
