 ## Introduction
 GuiLite is the smallest GUI library with 5000 lines of C++ code, could run on **all platforms**(e.g, iOS, Android, Linux, Windows, macOS, Docker and MCU without OS), and work with **many languages**(e.g. Swift, Java, Javascript, C#, Golang).
-- ✂️Small: Only 5 KLOC, independent of any OS and any third party library - Easy to build adn run
-- ⚡Fast: Render GUI within one invoking -  Make GUI runs quickly and smoothly
