-#1.Overview
-Littlevgl is an Open-source Embedded GUI Library. We definde an UI APP, and it can be running in 3 scenarios.
-1. Native Linux. The App code built into Linux executables.
-2. WASM VM for Different platform. WASM VM and native extension being built into Linux and Zephyr platforms. With WASM VM inside, many WASM APP can run on top of it.
-3. WASM APP. This kind of binary can be run on WASM VM.

+##Introduction
 
-#2.Install required SDK and libraries.
-##1. 32 bit SDL(simple directmedia layer) 
-###a. Use apt-get
-sudo apt-get install libsdl2-dev:i386
-###b. Install from source
-www.libsdl.org
-`./configure C_FLAGS=-m32 CXX_FLAGS=-m32 LD_FLAGS=-m32`
- ` ./make`
-`./sudo make install`
-##2. Install EMSDK
-    https://emscripten.org/docs/tools_reference/emsdk.html
-##3. Cmake
-     CMAKE version above 3.13.1.
-#3.Build & Run
-##1. Build and run on Linux
-###a. Build
-`./build.sh`
-    All binaries are in "out", which contains "host_tool", "vgl_native_ui_app", "TestApplet1.wasm" and "vgl_wasm_runtime".
-###b.Run native Linux application
-`./vgl_native_ui_app`
-###c.Run WASM VM Linux applicaton & install WASM APP
-####1. Start vgl_wasm_runtime in server mode
-`./vgl_wasm_runtime -s`
-####2. Install wasm APP
-`./host_tool -i TestApplet1 -f TestApplet1.wasm`
-##2. Build and run on zephyr
-WASM VM and native extension method can be built into zephyr, Then we can install wasm app into STM32.
-###1.Build wasm into Zephyr system
-####a. clone zephyr source code
-`git clone https://github.com/zephyrproject-rtos/zephyr.git`
-####b. copy samples
-    `cd zephyr/samples/`
-    `cp -a <iwasm_root_dir>projects/littlevgl/vgl-wasm-runtime vgl-wasm-runtime`
-    `cd vgl-wasm-runtime/zephyr_build`
-####c. create a link to wamr core
-   ` ln -s <iwasm_root_dir>/core core`
-####d. build source code
-We use nucleo_f767zi, which is almost the same as nucleo_f746zg, except SRAM size in DTS.
-Duplicate zephyr board support of nucleo_f746zg, then change SRAM size to 512KB.
-    `mkdir build && cd build`
-    `source ../../../../zephyr-env.sh`
-    `cmake -GNinja -DBOARD=nucleo_f767ZI ..`
-   ` ninja flash`
-
-###2. Test on STM32 NUCLEO_F767ZI with ILI9341 Display with XPT2046 touch.
-####a. Hardware Connetions

-####b. Install wasm app to zephyr using host_tool
-First connect PC and STM32 with UART. Then install use host_tool.
-`./host_tool -D /dev/ttyUSB0 -i TestApplet1 -f TestApplet1.wasm`
+This project aims to demonstrate wasm app management and programming model of WAMR.
 
+##Build all binaries
+Execute the build.sh script then all binaries including wasm application files would be generated in 'out' directory.
+`./build.sh`
