 #### Steps
+##### 1. add jars of chunjun 
+1) Find directory of jars:
+ if you build this project using maven, the directory name is 'chunjun-dist' ;
+ if you download tar.gz file from release page, after decompression, the directory name would be like 'chunjun-assembly-1.12-SNAPSHOT-chunjun-dist'.
+
+2) Copy jars to directory of Flink lib, command example:
+```shell
+cp -r chunjun-dist $FLINK_HOME/lib
+```
+Notice: this operation should be executed in all machines of Flink cluster, otherwise some jobs will fail because of ClassNotFoundException.

 ```shell

 After the startup is successful, the default port of Flink Web is 8081, which you can configure in the file of 'flink-conf.yaml'. We can access the 8081 port of the current machine to enter the flink web of standalone cluster.

 #### 提交步骤
 
-##### 1. 启动Flink Standalone环境
+##### 1. 添加chunjun依赖包
+1) 根据实际情况找到依赖文件:
+ 通过maven编译的方式构建项目时，依赖文件目录为'chunjun-dist';
+ 通过官网下载压缩包解压使用时，依赖文件目录为解压后的目录，例如'chunjun-assembly-1.12-SNAPSHOT-chunjun-dist'
+
+2) 将依赖文件复制到Flink lib目录下,例如
+```shell
+cp -r chunjun-dist $FLINK_HOME/lib
+```
+注意: 这个复制操作需要在所有Flink cluster机器上执行，否则部分任务会出现类找不到的错误。
+
+##### 2. 启动Flink Standalone环境
 
 ```shell
 sh $FLINK_HOME/bin/start-cluster.sh
 ```
 
 启动成功后默认端口为8081，我们可以访问当前机器的8081端口进入standalone的flink web ui
