 # Managed Component Light
 
-This example is configured by default to work with the ESP32-S3, which has the RGB LED GPIO set as pin 48 and the BOOT button on GPIO 0.
+This example sets automatically the RGB LED GPIO and BOOT Button GPIO based on the default pin used by the selected Devkit Board.
 
 This example creates a Color Temperature Light device using the esp_matter component downloaded from the [Espressif Component Registry](https://components.espressif.com/) instead of an extra component locally, so the example can work without setting up the esp-matter environment.
 
-See the [docs](https://docs.espressif.com/projects/esp-matter/en/latest/esp32/developing.html) for more information about building and flashing the firmware.

 (*) Google Home Assistant requires the user to set up a Matter Light using the [Google Home Developer Console](https://developers.home.google.com/codelabs/matter-device#2). It is necessary to create a Matter Light device with VID = 0xFFF1 and PID = 0x8000. Otherwise, the Light won't show up in the GHA APP. This action is necessary because the Firmware uses Testing credentials and Google requires the user to create the testing device before using it.

After that, the device needs to be commissioned again. Previous setups done in the Smartphone APP won't work again; therefore, the virtual device shall be removed from the APP.

 ## Building the Application using Wi-Fi and Matter
 
 Use ESP-IDF 5.1.4 from https://github.com/espressif/esp-idf/tree/release/v5.1  
 This example has been tested with Arduino Core 3.0.4
 
 The project will download all necessary components, including the Arduino Core.  
-Run `idf.py SDKCONFIG_DEFAULTS="sdkconfig.defaults.<SOC>.idf" -p <PORT> flash monitor`
+Run `idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults.<SOC>.idf" -p <PORT> flash monitor`
 
 Example for ESP32-S3/Linux | macOS:  
-`idf.py SDKCONFIG_DEFAULTS="sdkconfig.defaults.esp32s3" -p /dev/ttyACM0 flash monitor`
+```
+idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults.esp32s3" -p /dev/ttyACM0 flash monitor
+```
 Example for ESP32-C3/Windows:  
-`idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults.esp32c3" -p com3 flash monitor`
+```
+idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults.esp32c3" -p com3 flash monitor
+```
 
 It may be necessary to delete some folders and files  before running `idf.py`  
-Linux/macOS: `rm -rf build managed_components sdkconfig dependencies.lock`  
-Windows: `rmdir /s/q build managed_components` and `del sdkconfig dependencies.lock`
+- Linux/macOS:
+  ```
+  rm -rf build managed_components sdkconfig dependencies.lock
+  ```  
+- Windows:
+  ```
+  rmdir /s/q build managed_components && del sdkconfig dependencies.lock
+  ```
 
 There is a configuration file for these SoC: esp32s3, esp32c3, esp32c6.
 Those are the tested devices that have a WS2812 RGB LED and can run BLE, Wi-Fi and Matter.
 
 In case it is necessary to change the Button Pin or the REG LED Pin, please use the `menuconfig`
 `idf.py menuconfig` and change the Menu Option `Light Matter Accessory`
