+### 下载SDK
+
+1. 访问SDK源码目录 [SIENGINE_SDK](https://gitlab.com/siengine-ubuntu-sdk/manifests) 查看具体的源码下载步骤
+2. `toolchain` 目录下的文件以`lfs`的形式存储，请根据目录下的`readme`文件操作，下载完成后手动解压工具链
+
+### 编译SDK
+
+1. 参考文档 [SE1000 Linux SDK 编译参考手册](https://gitlab.com/siengine-ubuntu-sdk/docs/-/blob/master/UM_SE1000_AIoT_Linux_SDK_User_Manual.pdf?ref_type=heads) 进行环境搭建和镜像编译
+
+
+2. 编译出来的相关固件将会存在 `deploy/build/` 目录下，请根据对应的 DDR 容量下载相应的 `LUN5` 固件替换目录下的 `lun5_fip.bin`

+
+## Download the SDK
+
+Visit the [SIENGINE_SDK](https://gitlab.com/siengine-ubuntu-sdk/manifests) source directory to view the detailed source download steps.
+The files in the `toolchain` directory are stored in `lfs` format. Please follow the instructions in the `readme` file within the directory. After downloading, manually extract the toolchain.
+
+## Compile the SDK
+
+Refer to the [SE1000 Linux SDK Compilation Reference Manual](https://gitlab.com/siengine-ubuntu-sdk/docs/-/blob/master/UM_SE1000_AIoT_Linux_SDK_User_Manual.pdf?ref_type=heads) for setting up the environment and compiling the image.
+The compiled firmware will be located in the `deploy/build/` directory. Please download the corresponding `LUN5` firmware based on the DDR capacity and replace the `lun5_fip.bin` in the directory.
