 # RotaryEncoderPCNT
 
-This is a 2-channel rotary (quadrature) encoder implementation, for the ESP32, on the Arduino platform. It uses the ESP32's built in pulse counter (PCNT) peripheral.
-
-Simply create a new `RotaryEncoderPCNT` object with the encoder's A and B pins, then call `.position()` to return the current position. The PCNT unit is set up to keep the encoder object updated in the background, handling interrupts, internal counter overflow, etc. for you.
-
-Note: `.position()` returns a signed 32-bit integer. If you expect to overflow that, you need to handle it.

 ### Compatibility
 - Requires Arduino ESP32 Core 3.0 or higher
 - Incompatible with ESP32-C2 and ESP32-C3, as they don't have PCNT units.
 
 ### Most Basic Example
-```
+```C++
 #include <RotaryEncoderPCNT.h>
 
 RotaryEncoderPCNT encoder(25, 12);
