 ## 7.7步骤打印
 
-liteFlow在执行每一条流程链后会打印步骤  
+liteFlow在执行每一条流程链后会打印步骤，这个步骤是程序实际执行的顺序  
 样例如下：
 
 ```
 a==>c==>m==>q==>p==>p1==>g
 ```
 
-当然你还可能看到这样的情况：
-
-```
-a==>c==>h(START)==>m==>p==>p1==>h(END)==>g
-```
-?> 其中h节点分start和end两个步骤，说明在h节点内调用了另一条流程。start和end之间的步骤就是另一条流程的步骤

 ## 7.8监控
 
 liteFlow提供了简单的监控，目前只统计一个指标：每个组件的平均耗时
