+# How to Build SOPHGO Deployment Environment
+
+## SOPHGO Environment Preparation
+SOPHGO supports compilation on linux, using Debian/Ubuntu as an example  
+The installation package consists of three files
+- [sophon-driver\_0.4.2\_$arch.deb](http://219.142.246.77:65000/sharing/KWqbmEcKp)
+- [sophon-libsophon\_0.4.2\_$arch.deb](http://219.142.246.77:65000/sharing/PlvlBXhWY)
+- [sophon-libsophon-dev\_0.4.2\_$arch.deb](http://219.142.246.77:65000/sharing/zTErLlpS7)
+
+$arch indicates the hardware architecture of the current machine. Run the following command to obtain the current server arch:
+```shell
+uname -m
+```
+Generally, the hardware architecture of x86_64 machines is amd64, so the hardware architecture is arm64:  
+```text
+- sophon-driver_0.4.2_$arch.deb
+- sophon-libsophon_0.4.2_$arch.deb
+- sophon-libsophon-dev_0.4.2_$arch.deb  
+```
+
+sophon-driver contains PCIe acceleration card drivers; sophon-libsophon contains the runtime environment (librarys, tools, etc); sophon-libsophon-dev contains the development environment (header files, etc.). If you install packages only on a deployment environment, you do not need to install sophon-libsophon-dev.
+You can perform the following steps to install:
+```shell
+#To install a dependency library, you only need to do this once:
+sudo apt install dkms libncurses5
+#install libsophon:
+sudo dpkg -i sophon-*.deb
+#Run the following command on the terminal, log out and then log in the current user to use commands such as bm-smi:
+source /etc/profile
+```
+The position of installation:：
+```text
+/opt/sophon/
+├── driver-0.4.2
+├── libsophon-0.4.2
+|    ├──bin
+|    ├──data
+|    ├──include
+|    └──lib
+└── libsophon-current->/opt/sophon/libsophon-0.4.2
+```
+
+## How to Build and Install C++ SDK
+After setting up the compilation environment, the compilation command is as follows：
+```bash
+# Download the latest source code
+git clone https://github.com/PaddlePaddle/FastDeploy.git
+cd FastDeploy  
+mkdir build && cd build
+
+# CMake configuration with Ascend
+cmake -DENABLE_SOPHGO_BACKEND=ON  \
+      -DCMAKE_INSTALL_PREFIX=${PWD}/fastdeploy-sophgo \
+      -DENABLE_VISION=ON \
+      ..
+
+# Build FastDeploy Ascend C++ SDK
+make -j8
+make install
+```  
+When the compilation is complete, the fastdeploy-sophgo directory is created in the current build directory, indicating that the FastDeploy library has been compiled.
+
+## Compiling Python FastDeploy Libraries
+After setting up the compilation environment, the compilation command is as follows：
+```bash
+# Download the latest source code
+git clone https://github.com/PaddlePaddle/FastDeploy.git
+cd FastDeploy/python
+export ENABLE_SOPHGO_BACKEND=ON
+export ENABLE_VISION=ON
+
+python setup.py build
+python setup.py bdist_wheel
+
+#After the compilation is complete, please install the whl package in the dist folder of the current directory.
+```
