+## Production (Clone) Mode
+
+- Fill in the optional `Zeppelin Production Note Directory` parameter to enable `Production Mode`.
+- In `Production Mode`, the target note gets copied to the `Zeppelin Production Note Directory` you choose. 
+`Zeppelin Task Plugin` will execute the cloned note instead of the original one. Once execution done, 
+`Zeppelin Task Plugin` will delete the cloned note automatically. 
+Therefore, it increases the stability as the modification to a running note triggered by `Dolphin Scheduler` 
+will not affect the production task.
+- If you leave the `Zeppelin Production Note Directory` empty, `Zeppelin Task Plugin` will execute the original note.
+- 'Zeppelin Production Note Directory' should both start and end with a `slash`. e.g. `/production_note_directory/`

 - Zeppelin Rest Endpoint：您的Zeppelin服务的REST Endpoint。
+- Zeppelin Production Note Directory：生产模式下存放克隆note的目录。
 - Zeppelin Parameters: 用于传入Zeppelin Dynamic Form的参数。
 
+## 生产（克隆）模式
+
+- 填上`Zeppelin Production Note Directory`参数以启动`生产模式`。
+- 在`生产模式`下，目标note会被克隆到您所填的`Zeppelin Production Note Directory`目录下。 
+`Zeppelin任务插件`将会执行克隆出来的note并在执行成功后自动清除它。 
+因为在此模式下，如果您不小心修改了正在被`Dolphin Scheduler`调度的note，也不会影响到生产任务的执行，
+从而提高了稳定性。 
+- 如果您选择不填`Zeppelin Production Note Directory`这个参数，`Zeppelin任务插件`将会执行您的原始note。
+'Zeppelin Production Note Directory'参数在格式上应该以`斜杠`开头和结尾，例如 `/production_note_directory/`。
