 **A [Bytecode Alliance][BA] project**
 
 [BA]: https://bytecodealliance.org/
 
 WebAssembly Micro Runtime (WAMR) is a standalone WebAssembly (WASM) runtime with small footprint. It includes a few parts as below:
-- A WebAssembly VM core (namely iwasm)
-- The supporting API's for the WASM applications
-- A mechanism for dynamic management of the WASM application
+- The "iwasm" VM core, supporting WebAssembly interpreter, ahead of time compilation (AoT) and Just-in-Time compilation (JIT)
 
+- The application framework and the supporting API's for the WASM applications
 
-Current Features of WAMR
-=========================
-- WASM interpreter (AOT is planned)
-- Provides embedding C API
-- Provides a mechanism for exporting native API's to WASM applications
-- Supports libc for WASM applications in two modes: the built-in libc subset for embedded environment and [WASI](https://github.com/WebAssembly/WASI) for standard libc
-- The WASM application framework and asynchronized app programming model
-- Supports for micro-service and pub-sub event inter-app communication models
-- Supports remote WASM application management from either host or cloud
-- Menu configuration for easy integration of application libraries
-
-Application framework architecture
-===================================
-
-By using the iwasm VM core, we are flexible to build different application frameworks for the specific domains.
+- The dynamic management of the WASM applications
 
-The WAMR has offered a comprehensive application framework for device and IoT usages. The framework solves many common requirements for building a real project:
-- Modular design for more language runtimes support
-- Inter application communication
-- Remote application management
-- WASM APP programming model and API extension mechanism

+iwasm VM core
+=========================
 
+### key features
 
+- Embeddable with the supporting C API's
+- Small runtime binary size (85K for interpreter and 50K for AoT) and low memory usage
+- Near to native speed by AoT 
+- AoT module loader works for both embedded OS and Linux system
+- Choices of WASM application libc support: the built-in libc subset for embedded environment or [WASI](https://github.com/WebAssembly/WASI) for standard libc
+- The mechanism for exporting native API's to WASM applications
 
-Build WAMR
-==========
+### Supported architectures and platforms
 
-## Build WAMR VM core
+The iwasm supports following architectures:
 
+- X86-64, X86-32
+- ARM, THUMB 
+- MIPS 
+- XTENSA
 
-WAMR VM core (iwasm) can support building for different target platforms:
-- Linux
-- Zephyr
-- MacOS
-- VxWorks
-- AliOS-Things
-- Intel Software Guard Extention (SGX)
+Following platforms are supported:
 
-See [Build WAMR VM core](./doc/build_wamr.md) for the detailed instructions.
+- [Linux](./doc/build_wamr.md#linux)
+- [Zephyr](./doc/build_wamr.md#zephyr)
+- [MacOS](./doc/build_wamr.md#macos)
+- [VxWorks](./doc/build_wamr.md#vxworks)
+- [AliOS-Things](./doc/build_wamr.md#alios-things)
+- [Intel Software Guard Extention (Linux)](./doc/build_wamr.md#linux-sgx-intel-software-guard-extention)
 
-## Libc building options
+Refer to [WAMR porting guide](./doc/port_wamr.md) for how to port WAMR to a new platform.
 
-WAMR supports WASI for standard libc library as well as a [built-in libc subset](./doc/wamr_api.md) for tiny footprint.
+### Build wamrc AoT compiler
 
-WASI is supported for following platforms and enabled by default building:
-- Linux
+Execute following commands to build **wamrc** compiler:
 
+```shell
+cd wamr-compiler
+./build_llvm.sh
+mkdir build
+cd build
+cmake ..
+make
+```
 
+After build is completed, create a symbolic link **/usr/bin/wamrc** to the generated wamrc.
 
-## Embed WAMR VM core
+### Build the mini product
 
-WAMR can be built into a standalone executable which takes the WASM application file name as input, and then executes it. In some other situations, the WAMR source code is embedded the product code and built into the final product.
+WAMR supports building the iwasm VM core only (no app framework) to the mini product.  The WAMR mini product takes the WASM application file name as input, and then executes it. For the detailed procedure, see **[build WAMR VM core](./doc/build_wamr.md)** and **[build and run WASM application](./doc/build_wasm_app.md)**.
 
-WAMR provides a set of C API for loading the WASM module, instantiating the module and invoking a WASM function from a native call.  See [Embed WAMR VM core](./doc/embed_wamr.md) for the details.
+### Embed WAMR VM core
 
-The WAMR application framework supports dynamically installing WASM application remotely by embedding the WAMR VM core. It can be used as reference for how to use the embedding API's.
+WAMR provides a set of C API for loading the WASM module, instantiating the module and invoking a WASM function from a native call.  For the details, see [embed WAMR VM core](./doc/embed_wamr.md).
 
 
-## Integrate  WAMR application library
 
-The WAMR provides an application framework which supports event driven programming model as below:
+Application framework
+===================================
 
-- Single thread per WASM app instance
-- App must implement system callbacks: on_init, on_destroy
+By using the iwasm VM core, we are flexible to build different application frameworks for the specific domains, although it would take quite some efforts. 
 
-Application programming API sets are available as below:
+The WAMR has offered a comprehensive framework for programming WASM applications for device and IoT usages. The framework supports running multiple applications, which are based on the event driven programming model. Here are the supporting API sets by the [WAMR application library](./doc/wamr_api.md) :
 
 - Timer
 - Micro service (Request/Response) and Pub/Sub inter-app communication
@@ -86,51 +85,82 @@ Application programming API sets are available as below:
 - Connectivity and data transmission
 - 2D graphic UI (based on littlevgl)
 
-See [WAMR application library](./doc/wamr_api.md) for the details.
+Every subfolder under  [WAMR application framework](./core/app-framework) folder is a compilation configurable component. The developers can copy the template folder to create new components to the application framework.  If a component needs to export native functions to the WASM application, refer to the [export_native_api.md](./doc/export_native_api.md) .
 
-One WAMR build can select a subset from the WAMR application library. Refer to the sample "simple" for how to integrate API sets into WAMR building.
 
 
+# Remote application management
 
-## Build WAMR with customized application library
+The WAMR application manager supports remote application management from host environment or the cloud through any physical communications such as TCP, UPD, UART, BLE, etc. Its modular design makes it able to support application management for different managed runtimes.
 
-When WAMR is integrated into a specific project, it probably includes additional project specific applications APIs which can be either expansion or modification to the standard WAMR application library.
 
-The extended application library should be created in the folder [core/iwasm/lib/app-libs](./core/iwasm/lib/app-libs/). See the [doc/export_native_api.md](./doc/export_native_api.md) for the details.
 
+<img src="./doc/pics/wamr-arch.JPG" width="80%">
 
+The tool [host_agent](./test-tools/host-tool) communicates to the WAMR app manager for installing/uninstalling the WASM applications on companion chip from host system. And the [IoT App Store Demo](./test-tools/IoT-APP-Store-Demo/) shows the conception of remotely managing the device applications from cloud.
 
-# Create WASM application SDK
 
-When a customized WAMR runtime is shipped with the products, an associated WASM application SDK should be distributed to the application developers in order to develop WASM applications for the product. At the most time, the WASM application SDK should match the version of the runtime distribution.
 
+WAMR SDK
+==========
 
-Typically a WASM APP SDK package contains following components:
+The **wamr-sdk** tools build the WAMR to both **runtime SDK** for embedding by your native codes and **APP SDK** for developing the WASM applications. A SDK profile presents a configuration of build parameters for the selection of CPU arch, software platforms, execution mode, libc and application framework components.
 
-* **WASI-SDK**: only needed when WASI is enabled in the runtime. It can be a link to the WASI-SDK GitHub or the full offline copy.
-* **sysroot** folder: only needed when WASI is not enabled in the runtime. copied from [test-tools/toolchain/sysroot](./test-tools/toolchain/sysroot)
-* **app-lib** folder: copied from [core/iwasm/lib/app-libs](./core/iwasm/lib/app-libs/)
-* **cmake toolchain** file: copied from [test-tools/toolchain/wamr_toolchain.cmake](./test-tools/toolchain/wamr_toolchain.cmake)
-* optionally with some guide documents and samples
+**Note**: [WASI-SDK](https://github.com/CraneStation/wasi-sdk/releases) version 7 and above should be installed before building the WAMR SDK.
 
+### Menu configuration for building SDK
 
+Menu configuration is supported for easy integration of runtime components and application libraries for  the target architecture and platform. 
 
-Build WASM applications
-===================================
+```
+cd wamr-sdk
+./menuconfig.sh
+```
+
+<img src="./doc/pics/wamr_menu_config.png" alt="wamr build menu configuration" style="zoom:80%;" />
+
+After the menu configuration is finished, the building process is automatically started. When the building gets successful, the SDK package is generated under folder $wamr-sdk/out/{profile}, and the header files of configured components were copied into the SDK package.
+
+The directory structure of a SDK package with profile name "simple":
+
+```
+simple/
+├── app-sdk
+│   ├── libc-builtin-sysroot
+│   │   ├── include
+│   │   └── share
+│   └── wamr-app-framework
+│       ├── include
+│       │   ├── bi-inc
+│       │   └── wa-inc
+│       ├── lib
+│       └── share
+└── runtime-sdk
+    ├── include
+    │   └── bi-inc
+    └── lib
+```
+
+The tool **build_sdk.sh** can be also directly executed by passing the configuration arguments, which is how each WAMR sample project builds the WAMR SDK for its own building profile.
+
+### Use Runtime SDK
+
+The folder "**runtime-sdk**" contains all the header files and library files for integration with project native code.
+
+### Build WASM applications with APP-SDK
+
+The folder “**app-sdk**” contains all the header files and WASM library for developing the WASM application. For C/C++ based WASM applications, the developers can use conventional cross-compilation procedure to build the WASM application.  Refer to [build WASM applications](./doc/build_wasm_app.md) for the details.
 
-WebAssembly as a new binary instruction can be viewed as a virtual architecture. If the WASM application is developed in C/C++ language,  developers can use conventional cross-compilation procedure to build the WASM application.  cmake is the recommended building tool and Clang is the preferred compiler. While emcc may still work but it is not guaranteed.
 
-Refer to [Build WASM applications](doc/build_wasm_app.md) for details.
 
 
 Samples and demos
 =================
 
-The WAMR samples are located in folder [./samples](./samples). A sample usually contains the WAMR runtime build, WASM applications and test tools. The WARM provides following samples:
-- [Simple](./samples/simple/README.md): The runtime is integrated with most of the WAMR APP libaries and multiple WASM applications are provided for using different WASM API set.
