+# Docker Images for Python Barcode Detection on ARM64 and ARM32
+This repository provides a guide on how to use the Dynamsoft Barcode Reader Python SDK within Docker containers designed for ARM64 and ARM32 architectures.
+
+## Building Docker Images for ARM64 and ARM32
+
+To build Docker images for ARM64 and ARM32, execute the following commands:
+
+```bash
+docker run --rm --privileged multiarch/qemu-user-static:register --reset
+docker build --platform linux/arm64 -f DockerfileArm64 -t <IMAGE-NAME> .
+docker build --platform linux/arm/v7 -f DockerfileArm32 -t <IMAGE-NAME> .  
+```
+
+## Running Python Barcode Detection in Docker Containers
+
+To run barcode detection using the Python script inside a Docker container, use these commands:
+
+```bash
+docker run --platform linux/arm64 -it --rm -v ${pwd}:/usr/src/myapp -w /usr/src/myapp <IMAGE-NAME> python pillow_test.py
+docker run --platform linux/arm/v7 -it --rm -v ${pwd}:/usr/src/myapp -w /usr/src/myapp <IMAGE-NAME> python pillow_test.py
+```
+
+**Try the Pre-built Images**
+
+You can also try the pre-built images directly:
+
+```bash
+docker run --platform linux/arm64 -it --rm -v ${pwd}:/usr/src/myapp -w /usr/src/myapp yushulx/dbr-arm64:1.0 python pillow_test.py
+docker run --platform linux/arm/v7 -it --rm -v ${pwd}:/usr/src/myapp -w /usr/src/myapp yushulx/dbr-arm32:1.0 python pillow_test.py
+```
+
+## Emulating Raspberry Pi
+Use [dockerpi](https://github.com/lukechilds/dockerpi) to test the performance of the Python Barcode SDK on Raspberry Pi emulators:
+
+```bash
+docker run -it lukechilds/dockerpi pi2
+docker run -it lukechilds/dockerpi pi3
+```
