-- getConfig and setConfig to reload the config file at runtime via discord commands
-- fixed wrong timestamps in some embeds (ty CommanderLook)

-# 1.0
-- feature parity with [the old bot](https://git.kageru.moe/kageru/discord-selphybot) (this does not include features that were broken in the old bot)

-# kagebot
-Kinda dead.
-
-This bot is a replacement for [my old one](https://git.kageru.moe/kageru/discord-selphybot) with a very simple premise:
-As much as possible should be configurable in a human-readable way.
-This will allow anyone to modify the config to host their own instance tailored to their own needs,
-and it allows server moderators to make changes without any coding experience. Even at runtime.
-I try to maintain a comprehensive default configuration as part of the repository
-because the past has taught me that I’m not good at updating readmes.
-
-## A few months after
-The bot has become somewhat specialized at this point,
-  but I think it should still be generally reusable if a similar use case arises.
-The implementation has kind of deteriorated into a playground for me
-  (adding arrow-kt and just generally trying out FP stuff)[1],
-  but it’s been running and moderating a 1000+ user server for over a year
-  with relatively little maintenance.
-
-[1]: While arrow is great, adding it to a project after the fact leads to a very weird combination of FP and non-FP constructs.
-Would not recommend in production. This was also built in an early version of arrow that still had `Kind` and other concepts that were scrapped later,
-but I don’t plan to update that ever. The bot can keep running as-is until it breaks.
