+# STM32 Getting Started Guide
+
+The stm32 platform uses
+[Matter](https://github.com/project-chip/connectedhomeip) sdk with FreeRTOS.

+
+---
+
+## Supported Chips
+
+The stm32 platform is supported on:
+
+-   [STM32WB5MM-DK](https://www.st.com/en/evaluation-tools/stm32wb5mm-dk.html)
+
+## Matter Example Applications
+
+Sample Matter applications are provided for the stm32 platform. They can be used
+to speed up development. You can find them in the samples with `/stm32`
+subfolder.
+
+## Building the Example Application
+
+-   [Set Up Matter Environment](./BUILDING.md)
+
+-   Set up STLINK tools
+
+    ```
+     apt-get install stlink-tools
+    ```
+
+-   Building the Application
+
+    If the lighting example is to be built:
+
+    ```
+    ./scripts/build/build_examples.py --target stm32-$stm32_BOARD-lighting build
+    ```
+
+-   The output image files are stored in the subdirectories under `out`, the
+    subdirectory name is the same as the argument specified after the option
+    `--target` when build the examples.
+
+-   After building the application, `ST-LINK` tool is used to flash it to the
+    board. Before flashing the application, you will need to flash the fuse and
+    the co processor binary. The co processor binary and fuse are available
+    [here](https://github.com/stm32-hotspot/stm32wb-matter-device-over-thread/tree/main/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x)
+    Dynamic Concurrent Mode BLE Thread for Matter (Supports Full BLE Stack 5.2
+    certified and Minimal Thread Device ready v1.3)
+
+    ```
+     sudo st-flash  write chip-stm32-lighting-example.bin 0x08000000
+
+    ```
+
+## Commissioning
+
+There is one commissioning modes supported by stm32 platform:
+
+### BLE-Thread mode
+
+1. Build and Flash
+2. The example will run automatically after booting the stm32 board.
+3. Restore factory settings using B1 button by pressing at least 10 seconds
+4. Commissioning with
+   [Chip-Tool](https://github.com/project-chip/connectedhomeip/tree/master/examples/chip-tool),for
+   example:
+
+    ```
+    ./chip-tool pairing ble-thread <node_id> <hex:xxx> <pin_code> <discriminator>
+    ```
+
+### Bluetooth LE advertising
+
+In this example, to commission the device onto a Matter network, it must be
+discoverable over Bluetooth LE. After powering up the device, the device will
+advertise automatically for 30 seconds. After this delay, you will need to reset
+the device to start the commissioning procedure.
+
+### Bluetooth LE rendezvous
+
+In Matter, the commissioning procedure is done over Bluetooth LE between a
+Matter device and the Matter controller(, where the controller has the
+commissioner role.
+
+To start the rendezvous, the controller must get the commissioning information
+from the Matter device. The data payload is encoded within a QR code, printed to
+the UART console.
+
+### Thread provisioning
+
+The provisioning operation, which is the Last part of the rendezvous procedure,
+involves sending the Thread network credentials from the Matter controller to
+the Matter device. As a result, the device joins the Thread network via a
+OpenThread border Router (OTBR) and can communicate with other devices in the
+network.
