+## 准备源码工程
+
+本库是基于OpenHarmony-v3.2-Beta1版本，在RK3568开发板上验证的，如果是从未使用过RK3568，可以先查看[润和RK3568开发板标准系统快速上手](https://gitee.com/openharmony-sig/knowledge_demo_temp/tree/master/docs/rk3568_helloworld)。
+
+### 准备系统Rom源码
+
+系统源码获取请参考：[OpenHarmony源码下载](https://gitee.com/openharmony/docs/blob/OpenHarmony-v3.2-Beta2/zh-cn/release-notes/OpenHarmony-v3.2-beta1.md)
+
+### 增加构建脚本及配置文件
+
+- 下载本仓库代码
+
+  ```
+  cd ~
+  git clone git@gitee.com:openharmony-sig/tpc_c_cplusplus.git --depth=1
+  ```
+
+- 三方库目录结构
+
+  ```
+  tpc_c_cplusplus/libmp3lame  #三方库libmp3lame的目录结构如下
+  ├── adapted               #存放三方库适配需要的代码文件
+  ├── docs                  #存放三方库相关文档的文件夹
+  ├── BUILD.gn              #构建脚本，支持rom包集成
+  ├── bundle.json           #三方库组件定义文件
+  ├── README.OpenSource     #说明三方库源码的下载地址，版本，license等信息
+  ├── README_zh.md        
+  ```
+
+- 将三方库拷贝到OpenHarmony源码的third_party目录下
+
+  ```
+  cp ~/tpc_c_cplusplus/libmp3lame ~/openharmony/third_party -rf
+  ```
+
+### 准备三方库源码
+
+```
+cd ~/openharmony/third_party/libmp3lame    #进入三方库目录
+git clone https://github.com/gypified/libmp3lame.git    #下载三方库源码
+```
+
+## 系统Rom中引入三方库
+
+准备完三方库代码后，我们需要将三方库加入到编译构建体系中。标准系统编译构建可以参考文档[标准系统编译构建指导](https://gitee.com/openharmony/docs/blob/OpenHarmony-3.2-Beta1/zh-cn/device-dev/subsystems/subsys-build-standard-large.md) 我们默认三方库是属于OpenHarmony的thirdparty子系统，如果需要自己定义子系统参考文档[如何为三方库组件中添加一个三方库](https://gitee.com/openharmony-sig/knowledge/blob/master/docs/openharmony_getstarted/port_thirdparty/README.md) 新增需要编译的组件,在OpenHarmony源码的vendor/hihope/rk3568/config.json文件中，新增需要编译的组件，如下代码段所示，在thirdparty子系统下面新增libmp3lame组件
+
+```
+    {
+      "subsystem": "thirdparty",
+      "components": [
+        {
+          "component": "musl",
+          "features": []
+        },
+        {
+          "component": "libmp3lame",
+          "features": []
+        }
+      ]
+    }
+```
+
+## 系统Rom中引入三方库测试程序
+
+libmp3lame原生库提供了测试用例，如需要引入测试程序，在OpenHarmony源码的vendor/hihope/rk3568/config.json文件,对应组件的features中打开编译选项：
+
+```
+{
+	"subsystem": "thirdparty",
+	"components": [
+	 {
+		"component": "musl",
+		"features": []
+	 },
+	 {
+		"component": "libmp3lame",
+		"features": [ "enable_mp3lame_test=true" ]
+	 }
+    ]
+}
+```
+
+## 编译工程
+
+在OpenHarmony源码根目录下
+
+```
+cd ~/openharmony
+```
+
+- 执行编译
+
+  ```
+  ./build.sh --product-name rk3568 --ccache
+  ```
+  
+- 生成文件的路径
+
+  可执行文件生成在out/rk3568/thirdparty/libmp3lame/lame，库文件生成在out/rk3568/obj/thirdparty/libmp3lame目录下
+
+## 运行效果
+
+将编译生成的库和测试文件放到板子上运行，为避免每次将文件推入设备都烧录整个镜像，我们使用hdc_std工具将文件推到开发板上
+
+- 首先将hdc_std工具编译出来 工具编译出来所在路径out/sdk/ohos-sdk/windows/toolchains/hdc_std.exe
+
+  ```
+  hb set     #源码根目录下使用hb set 选择产品ohos-sdk
+  hb build   #然后编译
+  ```
+
+- 将工具拷贝到Windows，可以为工具目录配置环境变量，也可以在工具所在目录打开windows命令行
+
+- 将编译生成的lame可执行文件及原生库下的测试文件testcase.wav准备好
+
+- 将准备好的文件推送到开发板，在windows命令行进行如下操作
+
+  ```
+  hdc_std shell mount -o remount,rw /     #修改系统权限为可读写
+  hdc_std file send lame /data         #将可执行文件推入开发板data目录
+  hdc_std file send testcase.wav /data  #将测试文件推入开发板data目录
+  hdc_std shell                          #进入开发板
+  ./lame testcase.wav testcase.mp3  #执行可执行文件编码生成MP3文件
+                                    #该组件不需要将库拷贝到/system/lib 或者/system/lib64目录下，因为可执行文件已经执行了编译生成的静态库
+  ```
+
+- 运行测试程序 效果如下图
