 ## INTRODUCTION

+### What's MiniGUI

+### MiniGUI and HybridOS
+
+[HybridOS](https://github.com/FMSoftCN/hybridos) is another large open source project
+initiated by FMSoft. It is a totally new open source operating system designed for
+embedded and smart IoT devices and cloud computing environment.
+
+In practice, MiniGUI and the software which are used to integrated with GPU
+constitute the graphics stack of HybridOS.
+
+HybridOS uses MiniGUI as the underlying windowing system, and the members of
+HybridOS project are now maintaining the whole graphics stack.
+The following chart shows the graphics stack of HybridOS:
+
+```
+  -----------------------------------------------
+ |           MiniGUI/HybridOS Apps               |
+ |-----------------------------------------------|
+ |           |         (Graphics Stack)          |
+ |           |              ---------------------|
+ |           |              | hiMesa             |
+ |           | hiCairo      |  ------------------|
+ |           | MiniGUI      |  | EGL for MiniGUI |
+ | C++ libs  | hiDRMDrivers |  | GL, GLES, VG    |
+ | C libs    | libDRM       |  | GPU drivers     |
+ |-----------------------------------------------|
+ |  Linux Kernel                                 |
+ |            -----------------------------------|
+ |           |        DRI and DRI Drivers        |
+  -----------------------------------------------
+```
+
+As shown in the chart above, the HybridOS graphics stack consists of
+the following software:
+
+- `libDRM` provides some user land APIs for Linux Direct Rendering Infrastructure.
+- `hiDRMDrivers` contains the drivers (user land drivers, not kernel drivers) for
+   MiniGUI DRM engine. The drivers implement the basic hardware accelerated
+   2D graphics operations of various GPUs for MiniGUI.
+- `hiMesa` is the Mesa derivative for HybridOS, while Mesa is the open source
+  implementation of OpenGL and other graphics APIs, including OpenGL ES
+  (versions 1, 2, 3), OpenCL, OpenMAX, and Vulkan. It contains the following
+  components:
+   + The implementation of OpenGL, OpenGL ES (v1, 2, 3), and other
+     graphics APIs.
+   + The EGL implementation for MiniGUI platform.
+   + The graphics drivers for various GPUs and a software driver called `swrast`.
+- `hiCairo` is the Cairo derivative for HybridOS. Cairo is a 2D vector graphics
+  library for Gtk. We provide support for MiniGUI backend in `hiCairo`.
