 ## 一. 简介
 
-`CGraph`中文名为【色丶图】，是一套无任何第三方依赖的跨平台图流程执行框架。通过`GPipeline`(流水线)底层调度，提供了包含依赖元素依次执行、非依赖元素并发执行在 eDAG 调度功能。
+`CGraph`中文名为【色丶图】，是一套无任何第三方依赖的跨平台图流程执行框架。通过`GPipeline`(流水线)底层调度，提供了包含依赖元素依次执行、非依赖元素并发执行，支持暂停、恢复、超时设定的 `eDAG` 调度功能。
 
 使用者只需继承`GNode`(节点)类，实现子类的`run()`方法，并根据需要设定依赖关系，即可实现任务的图化执行或流水线执行。还可以通过设定各种包含多节点信息的`GGroup`(组)，自行控制图的条件判断、循环和并发执行逻辑。
