 ## Features
 
-1. Support up to 8 encoders on one device.
+1. Quadrature decoding via PCNT peripheral.
+2. Configurable min/max/step values with float precision.
+3. Push-button support with debouncing.
+4. Multiple simultaneous encoders (up to 8).
+5. Event-based notification via esp_event (ISR context).
+6. Error statistics tracking for diagnostics.
