+   - Brief description of functionality
+   - Usage instructions with examples
+   - Any configuration requirements
+
+## Testing
+
+Before committing plugin changes:
+
+1. Check files are properly formatted: Run `make format`
+2. Check code style and linting: Run `make lint`
+3. Test the plugin functionality: Run `make test`
+4. Verify documentation accuracy
+5. Ensure all examples work as described

 - 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.
+- Search and Replace: Reply to any message with `s/search/replace/[flags]` to perform text substitution. Supports flags: `g` (global), `i` (case insensitive), `n` (regex pattern). Example: `s/hello/hi/gi` replaces all occurrences of "hello" with "hi" case-insensitively.
