+# Seata Saga StateMachine Designer
+
+A visual graph Seata Saga StateMachine Designer based on [GGEditor](https://github.com/alibaba/GGEditor).
+
+## run
+
+```sh
+$ git clone https://github.com/seata/seata.git
+$ cd saga/saga-statemachine-designer
+$ npm install
+$ npm start
+```
+
+## build a package
+```sh
+$ cd saga/saga-statemachine-designer
+$ npm build
+```
+
+copy 'index.html' and 'dist' directory to static html directory of web server
+
+## Usage
+To understand the state types of the state machine, please see [document of Saga](http://seata.io/zh-cn/docs/user/saga.html). After using the designer to complete the design of the state machine, you can click the 'Json View' button on the toolbar to switch to the Json view, and save the Json to the project of your own application. Although the Json generated by the designer is different from the standard Json of the Saga state machine (because the json generated by the designer has layout information), the state machine can be directly loaded and it will be converted into the Json of the Saga state machine standard.

+
+Seata Saga 状态机可视化图形设计器, 基于 [GGEditor](https://github.com/alibaba/GGEditor)
+
+## 运行
+
+```sh
+$ git clone https://github.com/seata/seata.git
+$ cd saga/saga-statemachine-designer
+$ npm install
+$ npm start
+```
+
+## 打包
+```sh
+$ cd saga/saga-statemachine-designer
+$ npm build
+```
+
+然后将index.html和dist目录拷贝到web server的静态页面目录下
+
+## 使用
+了解状态机的种状态类型,请看Saga的[文档](http://seata.io/zh-cn/docs/user/saga.html)。 通过设计器完成设计后可以点击工具栏的'Json View'按钮切换到Json视图,将Json拷贝保存到自己应用的工程里。虽然设计器生成的Json与Saga标准的Json有所差别(因为设计器生成的json带有布局信息),但状态机可以直接加载,它会将其转化成Saga状态机标准的Json。
