 ## Features
 
-- Support for multiple chat platforms (Slack, Telegram)
+- Support for multiple chat platforms (Slack (untested!), Telegram)
 - Plugin system for easy extension
 - Admin interface for managing channels and plugins
 - Message queue for asynchronous processing

 - Dice: Put `!dice` and wathever roll you want to perform.
 - Coin: Flip a coin and get heads or tails.
 
+### Utility
+
+- Remind Me: Reply to a message with `!remindme <duration>` to set a reminder. Supported duration units: y (years), mo (months), d (days), h (hours), m (minutes), s (seconds). Examples: `!remindme 1y` for 1 year, `!remindme 3mo` for 3 months, `!remindme 2d` for 2 days, `!remindme 3h` for 3 hours. The bot will mention you with a reminder after the specified time.
+
 ### Social Media
 
 - Twitter Link Expander: Automatically converts twitter.com and x.com links to fxtwitter.com links and removes tracking parameters. This allows for better media embedding in chat platforms.
