+## Integration with eKuiper
+
+BIE has integrated [eKuiper](https://github.com/lf-edge/ekuiper) since v2.4.3. Now, you can deploy and run it with one click through BIE's system application
+For eKuiper:version 1.8.0-alpha.2, you only need to add 'baetyl-ekuiper' field to the sysApps field when the node is created or modified.
+
+The eKuiper will connect to baetyl-broker by default, so that you can use baetyl-broker as an input source to leverage eKuiper
+s streaming data processing and rules engine capabilities for edge data.

+## ekuiper集成
+
+BIE从v2.4.3版本开始集成了[eKuiper](https://github.com/lf-edge/ekuiper)，现在，你可以通过BIE的系统应用一键下发并运行
+eKuiper:1.8.0-alpha.2版本，只需要在节点创建或修改时的sysApps字段中，新增'baetyl-ekuiper'字段即可。
+
+下发的eKuiper将默认连接到baetyl-broker，这样，你就可以通过baetyl-broker作为输入源，利用eKuiper
+的流式数据处理和规则引擎能力对边缘数据进行处理了。
