 A no-frills Discord command framework for [Eris](https://github.com/abalabahaha/eris).
 
 Yuuko's goal is to provide a solid base for Discord bots of all types and sizes, featuring easy support for modular project structures, multiple levels of configuration hooks, and first-class Typescript compatibility in a lightweight package with no extra dependencies. [Read the usage guide][usage] or [check the full API reference][docs].

It will continue to be updated to work with new versions of Eris, but it will probably not get any significant feature updates - including support for slash commands. The author of this project doesn't recommended the use of Eris-based frameworks, including Yuuko, for new projects at this time.
