+### Generate OTA Firmware For BR
+
+Can use this python
+[script](https://github.com/espressif/esp-thread-br/blob/main/components/esp_rcp_update/create_ota_image.py)
+to merge thread border router firmware and the RCP firmware
+
+```
+python create_ota_image.py --rcp-build-dir /path/to/rcp_image/dir --br-firmware /path/to/br_image --target-file ota_target_file.bin
+```
+
+Then can use the generated bin file to create a Matter OTA file normally.
