 # WeDPR-Lab-Java-SDK
 
-Label: Develop
-
 ## 如何体验WeDPR-Lab-Java-SDK
 
-WeDPR-Lab-Java-SDK通过JNI调用rust产生动态库实现的相应密码组件
+WeDPR-Lab-Java-SDK是WeDPR-Lab的Java客户端。
 
 ### 快速体验
 
-请在WeDPR-Lab-Java-SDK项目目录下执行
+请在WeDPR-Lab-Java-SDK项目目录下执行。
+
 ```bash
+# 下载仓库
+git clone -b develop https://github.com/WeBankBlockchain/WeDPR-Lab-Java-SDK.git && cd ./WeDPR-Lab-Java-SDK
 # 获取动态库
-curl -Lo https://github.com/WeBankBlockchain/WeDPR-Lab-Java-SDK/releases/download/v0.0.1/lab-core-dynamic-libs.tar.gz
+curl -LO https://github.com/WeBankBlockchain/WeDPR-Lab-Java-SDK/releases/download/v0.0.1/lab-core-dynamic-libs.tar.gz
 # 解压
-tar zxvf lab-core-dynamic-libs
+tar zxvf lab-core-dynamic-libs.tar.gz
 # 拷贝动态库至加载路径
-cp ./lab-core-dynamic-libs/* ./solution/vcl/src/main/resources/WeDPR_dynamic_lib/
+cp ./lab-core-dynamic-libs/* ./solution/vcl/src/main/resources/WeDPR_dynamic_lib
 # 编译项目
 bash ./gradlew clean build
 # 进入项目目录
 cd solution/vcl/dist/
 # 运行demo
 java -cp "apps/*:conf/:libs/*" com.webank.wedpr.vcl.DemoMain
 ```

-### 源码体验
-
-#### 下载动态库
-
-通过访问`https://github.com/WeBankBlockchain/WeDPR-Lab-Java-SDK/releases/tag/v0.0.1`，下载`lab-core-dynamic-libs.tar.gz
-`，解压后根据自己所处操作系统将动态库放置于solution/vcl/src/main/resources/WeDPR_dynamic_lib下
-
-*.dll -> windows
-
-*.dylib -> macOs
-
-*.so -> linux 需要为centos7.2或ubuntu16.04以上版本
-
-#### 编译动态库
-
-访问https://github.com/WeBankBlockchain/WeDPR-Lab-Core，编译develop分支，生成动态库
-
-#### 调用demo
-
-执行`com.webank.wedpr.vcl.DemoMain`查看调用示例，或使用gradle构建项目后在solution/vcl/dist下执行
-
-```bash
-java -cp "apps/*:conf/:libs/*" com.webank.wedpr.vcl.DemoMain
-```
-
-#### 查看JNI
-
-相应调用代码可以查看solution/vcl
