 ### Building firmware
 
+#### Docker
+
+```sh
+docker buildx build --target export --output type=local,dest=build .
+```
+
+Firmware binaries will be in `build/Release/` directory:
+- `z03mmc.bin` - firmware binary
+- `db15-0203-*.zigbee` - firmware with OTA header
+
+If `docker buildx` is unavailable, use standard Docker with volume mount:
+```sh
+docker build -t z03mmc .
+docker run --rm -v $(pwd)/build:/output/Release z03mmc
+```
+
