 ### What's MiniGUI

-MiniGUI aims to provide a fast, stable, full-featured, and cross-platform
-windowing and GUI support system, which is especially fit for
-embedded systems or smart IoT devices based-on Linux/uClinux, eCos, and other
-traditional RTOSes, such as RT-Thread, FreeRTOS, RTEMS, VxWorks, ThreadX,
-Nucleus, pSOS, uC/OS-II, OSE, and others.

-### App Frameworks on MiniGUI
+### HVML App Framework on MiniGUI

-MiniGUI and its components provides a lot of controls/widgets to
-help your develop GUI apps in C/C++ programming language. However,
-alternatively, you can choose one of the following frameworks to
-develop your apps in a easy-to-use programming language other than C/C++.
+MiniGUI and its components provide a lot of controls/widgets to help your develop GUI apps in C/C++ programming language.
+However, alternatively, you can use the following software to develop your apps in an easy-to-use programming language [HVML].

-* [HybridOS](https://gitlab.fmsoft.cn/HybridOS/hybridos) provides
-  a complete software stack to develop an app which have rich functions
-  and excellent expressive in HTML5, CSS3, and JavaScript.
-* [hiACEJS](https://gitlab.fmsoft.cn/HybridOS/hiACEJS) provides
-  a light-weight app framework in JavaScript.
+* [HVML] is a descriptive programming language proposed and designed by [Vincent Wei].
+* [PurC] is the prime interpreter of HVML written in C lauguage.
+* [xGUI Pro] is a full-featured HVML renderer based on the tailored WebKit engine.

-You can also choose [HybridOS Lite](https://gitlab.fmsoft.cn/HybridOS/hybridos-lite)
-to develop apps with excellent expressive for cost-sensitive devices in C/C++ language.
+In short, the above software suite provides an Electron-like solution that can help people develop cross-platform applications using web front-end technology.
+The difference is that the solution replaces JavaScript with HVML and Node.JS with PurC.
+It provides an entirely new application framework that isolates the interpreter and renderer from running in separate processes, which brings several benefits.
+It greatly reduces the size and resource consumption of the entire solution, improves the overall performance, promotes the interactive responsiveness,
+   and provides a simpler mechanism to integrate existing C/C++ code modules.

 ### MiniGUI and HybridOS
