 ## 二、使用步骤
 
 ### 2.1 获取`sdk`
-pom文件中引入依赖:
+
+有两种方法
+
+1. 通过本项目自己打包
+2. 这里有打包好的`sdk`，[直接下载](https://github.com/uduncloud/java-wallet-sdk/releases/tag/v2.0.2)
+
+### 2.2 使用`sdk`，参考 [udun-sdk-java-demo](https://github.com/uduncloud/udun-sdk-java-demo)
+1. 将`sdk`拷贝到项目中
+2. `pom.xml`引入`sdk`及其依赖包
 
 ```
 <dependency>
     <groupId>com.udun</groupId>
     <artifactId>udun-sdk-java</artifactId>
     <version>2.0.2</version>
+    <scope>system</scope>
+    <systemPath>${project.basedir}/src/lib/udun-sdk-java-2.0.2.jar</systemPath>
+</dependency>
+<dependency>
+    <groupId>cn.hutool</groupId>
+    <artifactId>hutool-all</artifactId>
+    <version>5.4.0</version>
 </dependency>
 ```
