-# GuiX
+# Azure RTOS GuiX
+
+Azure RTOS GUIX is a professional-quality package, created to meet the needs of embedded systems developers. Unlike alternative GUI solutions Azure RTOS GUIX is small, fast, and easily ported to virtually any hardware configuration that’s capable of supporting graphical output. Azure RTOS GUIX also delivers exceptional visual appeal and an intuitive and powerful API for application-level user interface development.
+
+Azure RTOS GUIX Studio provides a complete, embedded graphical user interface (GUI) application design environment, facilitating the creation and maintenance of all graphical elements in the application’s GUI. Azure RTOS GUIX Studio automatically generates C code that’s compatible with the Azure RTOS GUIX library, ready to be compiled and run on the target. 
+
+Azure RTOS GUIX Studio is available on the Microsoft Download Center.
+
+## Documentation
+
+Documentation for this library can be found here: http://docs.microsoft.com/azure/rtos/guix
+
+# Building and using the library
+
+## Prerequisites
+
+Install the following tools:
+
+* [CMake](https://cmake.org/download/) version 3.0 or later
+* [GCC compilers for arm-none-eabi](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
+* [Ninja](https://ninja-build.org/)
+
+## Cloning the repo
+
+```bash
+$ git clone https://github.com/azure-rtos/guix.git
+```
+
+## Building the threadx static library
+
+Each component of Azure RTOS comes with a composible CMake-based build system that supports many different MCUs and host systems. Integrating any of these components into your device app code is as simple as adding a git submodule and then including it in your build using the CMake command `add_subdirectory()`.
+
+While the typical usage pattern is to include threadx into your device code source tree to be built & linked with your code, you can compile threadx as a standalone static library to confirm your build is set up correctly.
+
+```bash
+$ cmake -Bbuild -DCMAKE_TOOLCHAIN_FILE=cmake/cortex_m4.cmake -GNinja .
+
+$ cmake --build ./build
+```
+
+# Repository Structure and Usage
+
+## Branches & Releases
+
+The master branch has the most recent code with all new features and bug fixes. It does not represent the latest General Availability (GA) release of the library.
+
+## Releases
+
+Each official release (preview or GA) will be tagged to mark the commit and push it into the Github releases tab, e.g. `v6.0-rel`.
