 # Electroniccats_PN7150 API Reference
 
-The `Electroniccats_PN7150` class enables Arduino library for I2C access to the PN7150 and PN7160 RFID/Near Field Communication chip.
+The `Electroniccats_PN7150` class enables Arduino library for I2C access to the PN7150 and PN7160 RFID/Near Field Communication chips.
 
 ## Class: `Electroniccats_PN7150`
 
-Include and instantiate the Electroniccats_PN7150 class. Creates a global NFC device interface object, attached to pins 7 (IRQ) and 8 (VEN) and using the default I2C address 0x28
+Include and instantiate the `Electroniccats_PN7150` class. Creates a global NFC device interface object, specifying the chip model (PN7150 or PN7160), attached to designated pins for IRQ and VEN, and using the default I2C address 0x28.
+
+### Initialization for PN7150
 
 ```c
 #include <Electroniccats_PN7150.h>
 
-Electroniccats_PN7150 nfc(PN7150_IRQ, PN7150_VEN, PN7150_ADDR);
+#define PN7150_IRQ   (8)
+#define PN7150_VEN   (7)
+#define PN7150_ADDR  (0x28)
+
+Electroniccats_PN7150 nfc(PN7150_IRQ, PN7150_VEN, PN7150_ADDR); // Creates a global NFC device interface object for PN7150
 ```
 
 - `uint8_t PN7150_IRQ`: IRQ pin for data interrupt.
-- `uint8_t PN7150_VEN`: "Reset" or "Enable" pin for device.
-- `uint8_t PN7150_ADDR`: Hexadecimal address for device, default `0x28` .
+- `uint8_t PN7150_VEN`: "Reset" or "Enable" pin for the device.
+- `uint8_t PN7150_ADDR`: Hexadecimal address for the device, default `0x28`.
