-Modbus Commands
+### Modbus Commands
 Turn LED ON: Send 01 06 00 05 00 01 [CRC] (writes 1 to register 5).
 
 Turn LED OFF: Send 01 06 00 05 00 00 [CRC] (writes 0 to register 5).
 
 Read Registers: Send 01 03 00 00 00 0A [CRC] (reads 10 registers starting from 0).
 
-Customization
+### Customization
 You can adjust settings at runtime:
 
+```cpp
 modbus.setSlaveAddress(0x02);        // Change slave address to 0x02
 modbus.setLedPin(12);                // Change LED pin to 12
 modbus.setLedRegisterIndex(7);       // Use register 7 for LED control
 modbus.setModbusBaudRate(115200);    // Change baud rate to 115200
+```
 
-Hardware Requirements
+## Hardware Requirements
 Any Arduino-compatible board with a serial interface (e.g., Uno, Mega, Nano).
 
 An LED connected to the specified pin (default: pin 13, onboard LED on most Arduino boards).
 
 A Modbus master device or software (e.g., Modbus Poll, QModMaster) for testing.
