+### Note on Commissioning:
+
+- **ESP32 & ESP32-S2** do not support commissioning over Bluetooth LE. For these chips, you must provide WiFi credentials directly in the sketch code so they can connect to your network manually.
+- **ESP32-C6** Although it has Thread support, the ESP32 Arduino Matter Library has been pre compiled using WiFi only. In order to configure it for Thread-only operation it is necessary to build the project as an ESP-IDF component and to disable the Matter WiFi station feature.
+- **ESP32-C5** Although it has Thread support, the ESP32 Arduino Matter Library has been pre compiled using WiFi only. In order to configure it for Thread-only operation it is necessary to build the project as an ESP-IDF component and to disable the Matter WiFi station feature.
+
+## Features
+
+- Matter protocol implementation for a color light device
+- Support for both WiFi and Thread(*) connectivity
+- RGB color control with HSV color model
+- State persistence using `Preferences` library
+- Button control for toggling light and factory reset
+- Matter commissioning via QR code or manual pairing code
+- Integration with Apple HomeKit, Amazon Alexa, and Google Home
+(*) It is necessary to compile the project using Arduino as IDF Component.
+
+## Hardware Requirements
+
+- ESP32 compatible development board (see supported targets table)
+- RGB LED connected to GPIO pins (or using built-in RGB LED)
+- User button for manual control (uses BOOT button by default)
+
+## Pin Configuration
+
+- **RGB LED**: Uses `RGB_BUILTIN` if defined, otherwise pin 2
+- **Button**: Uses `BOOT_PIN` by default
+
+## Software Setup
+
+### Prerequisites
+
+1. Install the Arduino IDE (2.0 or newer recommended)
+2. Install ESP32 Arduino Core with Matter support
+3. ESP32 Arduino libraries:
+   - `Matter`
+   - `Preferences`
+   - `WiFi` (only for ESP32 and ESP32-S2)
+
+### Configuration
+
+Before uploading the sketch, configure the following:
+
+1. **WiFi credentials** (if not using BLE commissioning - mandatory for ESP32 | ESP32-S2):
+   ```cpp
+   const char *ssid = "your-ssid";         // Change to your WiFi SSID
+   const char *password = "your-password"; // Change to your WiFi password
+   ```
+
+2. **LED pin configuration** (if not using built-in RGB LED):
+   ``` cpp
+    const uint8_t ledPin = 2;  // Set your RGB LED pin here
+    ```
+3.  **Button pin configuration** (optional):
+    By default, the `BOOT` button (GPIO 0) is used for the Light On/Off manual control. You can change this to a different pin if needed.
+    ```cpp
+    const uint8_t buttonPin = 0;  // Set your button pin here
+    ```
+
+## Building and Flashing
+
+1.  Open the `MatterColorLight.ino` sketch in the Arduino IDE.
+2.  Select your ESP32 board from the **Tools > Board** menu.
+3.  Connect your ESP32 board to your computer via USB.
+4.  Click the **Upload** button to compile and flash the sketch.
+
+## Expected Output
+
+Once the sketch is running, open the Serial Monitor at a baud rate of **115200**. The WiFi connection messages will be displayed only for ESP32 and ESP32-S2. Other targets will use Matter CHIPoBLE to automatically setup the IP Network. You should see output similar to the following, which provides the necessary information for commissioning:
+
+```
+Connecting to your-wifi-ssid
+.......
+WiFi connected
+IP address: 192.168.1.100
+
+Matter Node is not commissioned yet.
+Initiate the device discovery in your Matter environment.
+Commission it to your Matter hub with the manual pairing code or QR code
+Manual pairing code: 34970112332
+QR code URL: https://project-chip.github.io/connectedhomeip/qrcode.html?data=MT%3A6FCJ142C00KA0648G00
+Matter Node not commissioned yet. Waiting for commissioning.
+Matter Node not commissioned yet. Waiting for commissioning.
+...
+Initial state: ON | RGB Color: (0,0,255)
+Matter Node is commissioned and connected to the network. Ready for use.
+```
+
+## Using the Device
+
+### Manual Control 
+
+The user button (BOOT button by default) provides manual control:
+
+- **Short press of the button**: Toggle light on/off
+- **Long press (>5 seconds)**: Factory reset the device (decommission)
+
+### Smart Home Integration
+
+Use a Matter-compatible hub (like an Apple HomePod, Google Nest Hub, or Amazon Echo) to commission the device.
+
+#### Apple Home
+
+1. Open the Home app on your iOS device
+2. Tap the "+" button > Add Accessory
+3. Scan the QR code displayed in the Serial Monitor, or
+4. Tap "I Don't Have a Code or Cannot Scan" and enter the manual pairing code
+5. Follow the prompts to complete setup
+6. The device will appear as a color light in your Home app
+
+#### Amazon Alexa
+
+1. Open the Alexa app
+2. Tap More > Add Device > Matter
+3. Select "Scan QR code" or "Enter code manually"
+4. Complete the setup process
+5. The light will appear in your Alexa app
+
+#### Google Home
+
+1. Open the Google Home app
+2. Tap "+" > Set up device > New device
+3. Choose "Matter device"
+4. Scan the QR code or enter the manual pairing code
+5. Follow the prompts to complete setup
+
+## Code Structure
+
+The MatterColorLight example consists of the following main components:
+
+1.  **`setup()`**: Initializes hardware (button, LED), configures WiFi (if needed), sets up the Matter endpoint, restores the last known state from `Preferences`, and registers callbacks for state changes.
+2.  **`loop()`**: Checks the Matter commissioning state, handles button input for toggling the light and factory reset, and allows the Matter stack to process events.
+3.  **Callbacks**:
+    -   `setLightState()`: Controls the physical RGB LED.
+    -   `onChangeOnOff()`: Handles on/off state changes.
+    -   `onChangeColorHSV()`: Handles color changes.
+
+## Troubleshooting
+
+- **Device not visible during commissioning**: Ensure WiFi or Thread connectivity is properly configured
+- **RGB LED not responding**: Verify pin configurations and connections
+- **Failed to commission**: Try factory resetting the device by long-pressing the button. Other option would be to erase the SoC Flash Memory by using `Arduino IDE Menu` -> `Tools` -> `Erase All Flash Before Sketch Upload: "Enabled"` or directly with `esptool.py --port <PORT> erase_flash`
+- **No serial output**: Check baudrate (115200) and USB connection

+
+## Using the Device
+
+### Test Cycle
+
+The device operates in a continuous test cycle:
+
+1. **Commissioning Phase**: The device waits for Matter commissioning. It displays the manual pairing code and QR code URL in the Serial Monitor.
+2. **Commissioned Phase**: Once commissioned, the device is connected to the Matter network and ready for use.
+3. **Automatic Decommissioning**: After 30 seconds, the device automatically decommissions itself.
+4. **Repeat**: The cycle repeats, allowing you to test the commissioning process multiple times.
+
+### Smart Home Integration
+
+Use a Matter-compatible hub (like an Apple HomePod, Google Nest Hub, or Amazon Echo) to commission the device during each test cycle.
+
+#### Apple Home
+
+1. Open the Home app on your iOS device
+2. Tap the "+" button > Add Accessory
+3. Scan the QR code displayed in the Serial Monitor, or
+4. Tap "I Don't Have a Code or Cannot Scan" and enter the manual pairing code
+5. Follow the prompts to complete setup
+6. The device will appear as an on/off light in your Home app
+7. After 30 seconds, the device will automatically decommission and the cycle will repeat
+
+#### Amazon Alexa
+
+1. Open the Alexa app
+2. Tap More > Add Device > Matter
+3. Select "Scan QR code" or "Enter code manually"
+4. Complete the setup process
+5. The light will appear in your Alexa app
+6. After 30 seconds, the device will automatically decommission and the cycle will repeat
+
+#### Google Home
+
+1. Open the Google Home app
+2. Tap "+" > Set up device > New device
+3. Choose "Matter device"
+4. Scan the QR code or enter the manual pairing code
+5. Follow the prompts to complete setup
+6. After 30 seconds, the device will automatically decommission and the cycle will repeat
+
+## Code Structure
+
+The MatterCommissionTest example consists of the following main components:
+
+1. **`setup()`**: Configures WiFi (if needed), initializes the Matter On/Off Light endpoint, and starts the Matter stack.
+2. **`loop()`**: Checks the Matter commissioning state, displays pairing information when not commissioned, waits for commissioning, and then automatically decommissions after 30 seconds to repeat the cycle.
+
+## Troubleshooting
+
+- **Device not visible during commissioning**: Ensure WiFi or Thread connectivity is properly configured
+- **Failed to commission**: Try waiting for the next cycle after decommissioning. Other option would be to erase the SoC Flash Memory by using `Arduino IDE Menu` -> `Tools` -> `Erase All Flash Before Sketch Upload: "Enabled"` or directly with `esptool.py --port <PORT> erase_flash`
+- **No serial output**: Check baudrate (115200) and USB connection
+- **Device keeps decommissioning**: This is expected behavior - the device automatically decommissions after 30 seconds to allow continuous testing
