 ### Using the DeleteConfiguration Sketch
 
 Open Arduino IDE and on the left side open the **Library Manager**. Search for **Arduino_NetworkConfigurator** and download it. Once it is downloaded go to **File > Examples > Arduino_NetworkConfigurator > Utility > DeleteConfiguration**, this will open a new example sketch. Select your board and port then upload this example sketch to your board. When the sketch has been uploaded you can look at the serial monitor to monitor the progress and troubleshoot if needed.
 
 The sketch can also be found [here](https://github.com/arduino-libraries/Arduino_NetworkConfigurator/blob/main/examples/utility/DeleteConfiguration/DeleteConfiguration.ino).

+#### How to use the Reconfiguration pin in your sketch
+
+If you want to use the Reconfiguration pin in your sketch, you can add a custom callback function to be fired every time the pin’s state changes.
+
+1. Define a function having this signature: `void func(void)`
+Example:
+```
+void onReconfigurationPinInterrupt()
+```
+2. Pass the callback function to the `NetworkConfigurator`, adding this line in the `initProperties()` function of the `thingProperties.h`
+```
+NetworkConfigurator.addReconfigurePinCallback(onReconfigurationPinInterrupt);
+```
+
+#### Change the Reconfiguration pin
+
+Despite the default reconfiguration pin, you can change it using the following code:
+```
+NetworkConfigurator.setReconfigurePin(your_pin);
+```
+in the `initProperties()` function of the `thingProperties.h`
+
+The new pin must be in the list of digital pins usable for interrupts. 
+Please refer to the Arduino documentation for more [details](https://docs.arduino.cc/language-reference/en/functions/external-interrupts/attachInterrupt/).
+
+#### Disable the Reconfiguration feature
+
+To disable the reconfiguration procedure, use the following function:
+```
+NetworkConfigurator.setReconfigurePin(DISABLE_PIN);
+```
+in the `initProperties()` function of the `thingProperties.h`
