+### Commissioning QR Code Change
+
+In this section, you will learn how to change the default commissioning QR code of your Nano Matter.
+
+![Unique QR Codes for your Matter devices](assets/new-qr-codes.png)
+
+Configuring your Nano Matter with a unique provisioning ID will allow you to:
+
+- Have a unique QR code for each one of your boards (end-devices).
+- Commission several Nano Matter boards to the same network with no conflicts.
+- Prepare your Nano Matter final product for field deployment.
+
+#### Requirements 
+
+The following requirements are needed:
+
+- Make sure the **Arduino IDE** and the **Silicon Labs Arduino Core** are both installed.
+- Make sure there is only **one** board connected to your computer at a time.
+- Flash your desired Matter sketch.
+- Clone the [Arduino Matter Provision Tool](https://github.com/silabs-bozont/arduino_matter_provision) repository on your local machine.
+
+#### Flashing the New Configuration
+
+To flash the new configuration, follow the steps below:
+
+- Navigate to the repository directory in your terminal.
+- The command has the following structure:
+
+  `python arduino_matter_provision.py <board_name> <config_number>`
+
+- Update the `board_name` with `nano_matter` and the `config_number` with `1` (or any other number),
+
+  E.g.: `python arduino_matter_provision.py nano_matter 1`
+
+- Run the script to change the provisioning data using the given structure.
+
+  ![Running the script](assets/qr-code-change.gif)
+
+Now, you can open the IDE Serial Monitor and see the new commissioning credentials. It is not neccesary to upload your Matter sketch again. 
+
+The Nano Matter default provisioning data is the following:
+
+- Manual Pairing Code: 34970112332
+- QR code URL: https://project-chip.github.io/connectedhomeip/qrcode.html?data=MT%3A6FCJ142C00KA0648G00
+
+After updating the provisioning data, you will see a new pairing and QR code, for example:
+
+- Manual Pairing Code: 00417637863
+- QR code URL: https://project-chip.github.io/connectedhomeip/qrcode.html?data=MT%3A8YT00-D000CQ-01VB10

 ### Device Decommissioning 
 
 If you have a Matter device configured and working with a _specific platform_, for example with the Google Home ecosystem, and you want to integrate it with Alexa or Apple Home instead, you need to decommission it first from the previous service.
