-## Purpose
+## 目的
 Full automated or user code driven navigation system.
+
+全自动化用户代码驱动导航系统。
+
 With this system you can define menus, submenus, input fields and other iteration objects that deal with all input/output and can call user defined handler as a result of user iteration.
+
+使用这个系统，你可以定义菜单、子菜单、输入字段和其他迭代对象来处理所有的输入输出，并且可以调用用户定义的处理程序作为用户迭代的结果。
+
 The user function can be operated as a single action called on click/enter or as a event driven function responding to focus In/Out or Enter/Esc events.
+
+用户函数可以作为单一的被称之为 click/enter 的动作，或者作为事件驱动函数响应 In/Out 或 Enter/Esc 焦点事件。
+
 The system is designed as a non blocking polling system, allowing concurrent task to run.
+
+系统被设计为非阻塞式轮询系统，允许运行当前任务。
+
 Optionally the system can be operated in semi-automated mode, issuing navigation command from user code.
 
+系统也可选半自动运行模式，从用户代码发出导航命令。
+

 - Easy to define menus (macros).
+- 容易定义菜单（宏）
 - Minimalistic user code base.
+- 极简用户代码库
 - Fields edit values hooked to existing program variables (references).
+- 字段编辑的值与现有程序变量挂钩
 - Editing text fields with per character validation.
