 ### What's MiniGUI
 
-MiniGUI is a mature cross-platform windowing system and a GUI (Graphics
-User Interface) support system for embedded systems and smart IoT devices.
-This is the version 5.0.x of MiniGUI maintained by WEI Yongming.
+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.
 
-MiniGUI is released under GPLv3 and the dual-licensing applies to commercial
-use.
+This is the source tree of MiniGUI Core, which provides the windowing and graphics interfaces as well as a lot of standard controls (toolkit).

+MiniGUI is released under GPLv3 and the dual-licensing applies to commercial use.
+In December 1998, the initiator of FMSoft, [Vincent Wei], began to develop MiniGUI under the GNU General Public License (GPL).
+In September 2002, the core developers of MiniGUI founded [FMSoft] and started the commercial marketing with the free software.
+By now, FMSoft still continues to release MiniGUI as a free software project.
 
-This is the source tree of MiniGUI Core, which provides the windowing

-### MiniGUI Components
-
-Besides MiniGUI Core, FMSoft also provides some components
-for the developers to develop app much easier:
-
-* mGUtils: A MiniGUI component which contains miscellaneous utilities
-  like `ColorSelectionDialogBox`, `FileOpenDialogBox`, and so on.
-* mGPlus: A MiniGUI component which provides support for advanced graphics
-  functions like path, gradient, anti-aliased stretch, and color combination.
-* mGEff: mGEff provides an animation framework for MiniGUI app.
-  It also provides some popular UI/UE special effects.
-* mGNCS: This component provides a new control set for MiniGUI app.
-* mGNCS4Touch: This component provides some new controls, which are
-  compliant to the new control API spec of mGNCS, for devices with
-  touch screens.
-
-There are also some legacy MiniGUI components. But we will not maintain these
-components since MiniGUI v3.2.0:
-
-* mGi: An input method component for MiniGUI. This component provides
-  some typical input methods (such as soft keyboard, hand-writing, and predict
-  text input for mobile phone) for MiniGUI apps.
-* mGp: A printing component for MiniGUI. By using mGp, you can print
-  out the graphics created by MiniGUI app to general-purpose printers.
-* mG3d: A simple three-dimension component for MiniGUI. This component
-  provides a simple 3D API for app. You can use mG3d to create simple
-  3D UI.
-
-MiniGUI is a free software project. In December 1998, the initiator of
-FMSoft, Wei Yongming, began to develop MiniGUI under the GNU General Public
-License (GPL). In September 2002, the core developers of
-MiniGUI founded FMSoft and started the commercial marketing with
-the free software. By now, FMSoft still continues to release MiniGUI
-as a free software project.

-You can download the source code tarball of MiniGUI and the dependent libraries
-from the download zone of the site:
+For the live demos, source tarballs, and cases of MiniGUI, you can refer to the following website:
 
 <http://www.minigui.com>
 
-### Open Source Apps Based-on MiniGUI
+### HVML App Framework on MiniGUI
 
-FMSoft also releases some open source apps for MiniGUI on the site above,
-for examples:
+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].
 
-* `mDolphin`, licensed under Apache 2.0, is a full-featured
-  WEB/WAP browser, which is developed based on the open source browser
-  core WebKit and uses MiniGUI as its underlying graphics support system.
-* `mGallery`, licensed under Apache 2.0, intends to
-  provide a total solution for PMP (Portable Multimedia Player),
-  which uses MiniGUI as the graphics platform.
-* `mSpider`, licensed under GPL 3.0, intends to provide a
-  light-weight MiniGUI-based web browser (HTML 3.2 and part JavaScript)
-* `mEagle`, licensed under GPL 3.0, is an embedded GIS development platform
-  which addresses the needs of map browse, query, analysis, etc
+* [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.
+
+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
