 ## Introduction
-- GuiLite is a barebone UI framework with 5000 lines of C++ code, it runs on **all platforms**(e.g, iOS, Android, Linux, Windows, macOS, Docker and **MCU with or without OS**).
+- GuiLite is the smallest GUI library with 5000 lines of C++ code, it runs on **all platforms**(e.g, iOS, Android, Linux, Windows, macOS, Docker and **MCU with or without OS**).
 - GuiLite is embeddable, it runs inside other UI frameworks(e.g, Qt, MFC, Winform, Cocoa). You could use GuiLite features and host UI features simultaneously.
 - GuiLite render UI by itself, independent of OS & Grphic library.
 - GuiLite could work with many languages(e.g. Swift, Java, C#, Golang).

+1. Just 5,000 line C++ code
+2. Only use basic C++ feature(class, virtual function), no complex syntax
+3. All rendering base on draw_pixel, no algorithm

 ## GuiLite是什么鬼？
-- GuiLite（超轻量UI框架）是5千行代码的**全平台UI框架**，可以完美运行在iOS，Android，Linux（ARM/x86-64），Windows（包含VR），Mac，Docker和**有(无)操作系统的MCU**上。
+- GuiLite是5千行代码的**全平台UI框架**，可以完美运行在: iOS，Android，Linux（ARM/x86-64），Windows（包含VR），Mac，Docker和**有(无)操作系统的MCU**上。
 - GuiLite可以嵌入在iOS、Android、MFC、QT等其他UI系统中，让你的界面集百家之长，又不失个性。
 - GuiLite与操作系统及第三方图形库无关，甚至也可以运行在无OS的单片机环境。
 - GuiLite鼓励混合编程，开发者可以用GuiLite接管UI部分，用Swift，Java，Golang，C#，Python开发业务部分。

+GuiLite是最简单，易学的GUI库。
+1. 只有5千行C++代码
+2. 只使用C++的基本特性（类和虚函数），不涉及复杂语法
+3. 图形绘制以描点为基础，不使用任何算法
+4. 设计简单，并配有丰富的文档和QQ开发群在线支持。
