 Base Discord bot framework
 
 ## Introduction
-bolt is a wrapper for Discordgo to provide very quick and easy setup for simple Discord bots. The only code required to run bolt is the command handler functions, this provides developers with the ability to have text-based commands on a Discord server without all the bootstrapping and setup usually required. Any strings returned from the Payload function will be sent back to the Discord server as a reply to the command message.

 ## Basic Usage
-bolt allows developers to create a Discord bot with simply a discord bot token and a few lines of Go code, the below example creates a Discord bot and registers three commands: ".ping", ".time", and ".role"
