It includes some non-music related modules as well, like a tag system, configurable server greetings, Google Images, Danbooru and Imgur search, among other stuff.
It's built on top of the FocaBotCore framework and Discordie. It's easy to create your own modules.
To learn more about the available commands and filters, and how to host the bot yourself check the website.
