 WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime with small footprint, high performance and highly configurable features for applications cross from embedded, IoT, edge to Trusted Execution Environment (TEE), smart contract, cloud native and so on. It includes a few parts as below:
-- [**VMcore**](./core/iwasm/): A set of runtime libraries for loading and running Wasm modules. It supports rich running modes including interpreter, Ahead-of-Time compilation(AoT) and Just-in-Time compilation (JIT). WAMR supports two JIT tiers - Fast JIT, LLVM JIT, and dynamic tier-up from Fast JIT to LLVM JIT.
-- [**iwasm**](./product-mini/): The executable binary built with WAMR VMcore which supports WASI and command line interface.

 ### Key features
 - Full compliant to the W3C Wasm MVP
-- Small runtime binary size (core vmlib on cortex-m4f with tail-call/bulk memroy/shared memroy support, text size from bloaty)
-  * ~58.9K for fast interpreter
-  * ~56.3K for classic interpreter
-  * ~29.4K for aot runtime
-  * ~21.4K for libc-wasi library
-  * ~3.7K for libc-builtin library
+- Small runtime binary size (~85K for interpreter and ~50K for AOT) and low memory usage
 - Near to native speed by AOT and JIT
 - Self-implemented AOT module loader to enable AOT working on Linux, Windows, MacOS, Android, SGX and MCU systems
 - Choices of Wasm application libc support: the built-in libc subset for the embedded environment or [WASI](https://github.com/WebAssembly/WASI) for the standard libc

+# AssemblyScript_on_WAMR
+This project is based on [Wasm Micro Runtime](https://github.com/bytecodealliance/wasm-micro-runtime) (WAMR) and [AssemblyScript](https://github.com/AssemblyScript/assemblyscript). It implements some of the `wamr app framework` in *assemblyscript*, which allows you to write some applications in *assemblyscript* and dynamically installed on *WAMR Runtime*
+
+## Building
+To build the samples in this repo, you need `npm` on your system
+``` bash
+sudo apt install npm
+```
+
+Then install all the dependencies under the repo's root dir
+``` bash
+cd $repo_root
+npm install
+```
+
+Use the command to build all samples:
+``` bash
+npm run build:all
+```
+or you can build every sample individually:
+``` bash
+npm run build:timer
+npm run build:publisher
+npm run build:subscriber
+# ...
+```
+You will get the compiled wasm file under `build` folder
+
+Please refer to [package.json](./package.json) for more commands.
+
+## Run
+These applications require WAMR's application framework, you need to build WAMR first.
+
+``` bash
+cd ${WAMR_ROOT}/samples/simple
+./build.sh
+```
+
+You will get two executable files under `out` folder:
+
+`simple`: The wamr runtime with application framework
+
+`host_tool`: The tool used to dynamically install/uninstall applications
+
+1. Start the runtime:
+    ``` bash
+    ./simple -s
+    ```
+
+2. Install the compiled wasm file using `host_tool`:
+    ``` bash
+    ./host_tool -i app_name -f your_compiled_wasm_file.wasm
+    ```
+You can also use the WAMR's AoT compiler `wamrc` to compile the wasm bytecode into native code before you run them. Please refer to this [guide](../README.md#build-wamrc-aot-compiler) to build and install `WAMR AoT compiler`.
+
+After installing `wamrc`, you can compile the wasm file using command:
+``` bash
+wamrc -o file_name.aot file_name.wasm
+```
+and you can install the AoT file to the runtime:
+``` bash
+./host_tool -i app_name -f your_compiled_aot_file.aot
+```
+
+## Development
+You can develop your own application based on the `wamr_app_lib` APIs.
+
+### Console APIs
+``` typescript
+function log(a: string): void;
+function log_number(a: number): void;
+```
+
+### Timer APIs
+``` typescript
+function setTimeout(cb: () => void, timeout: i32): user_timer;
+function setInterval(cb: () => void, timeout: i32): user_timer;

+
+You should export the `on_timer_callback`, `on_request` and `on_response` in your application entry file, refer to the samples for example.
+
+To build your application, you can use `asc`:
+``` bash
+asc app.ts -b build/app.wasm -t build/app.wat --sourceMap --validate --optimize
+```
+or you can add a command into [package.json](./package.json):
+``` json
+"build:app": "asc app.ts -b build/app.wasm -t build/app.wat --sourceMap --validate --optimize",
+```

+# Application framework
+
+By using the WAMR VM core, we are flexible to build different application frameworks for the specific domains, although it would take quite some effort.
+
+The WAMR has offered a comprehensive framework for programming WASM applications for device and IoT usages. The framework supports running multiple applications, that are based on the event driven programming model. Here are the supporting API sets by the [WAMR application framework library](../doc/wamr_api.md) :
+
+- Timer,  Inter-app communication (request/response and pub/sub), Sensor, Connectivity and data transmission, 2D graphic UI
+
+Browse the folder  [core/app-framework](./app-framework) for how to extend the application framework.
+
+
+## Directory structure
+This folder "app-native-shared" is for the source files shared by both WASM APP and native runtime  
+
+- The c files in this directory are compiled into both the WASM APP and runtime.
+- The header files for distributing to SDK are placed in the "bi-inc" folder.
+
+This folder "template" contains a pre-defined directory structure for a framework component. The developers can copy the template folder to create new components to the application framework.  
+
+Every other subfolder is framework component. Each component contains two library parts: **app and native**.  
+
+- The "base" component provide timer API and inter-app communication support. It must be enabled if other components are selected.
+- Under the "app" folder of a component, the subfolder "wa_inc" holds all header files that should be included by the WASM applications
+
+## Application framework basic model
+
+The app framework is built on top of two fundamental operations:
+
+- [Native calls into WASM function](../../doc/embed_wamr.md)
+
+- [WASM app calls into native API](../../doc/export_native_api.md)
+
+Asynchronized programming model is supported for WASM applications
+
+- Every WASM app has its own sandbox and thread
+
+- Queue and messaging
+
+<img src="../../doc/pics/app_framework.PNG" style="zoom:67%;" />
+
+
+
+## Customized building of app framework
+
+A component can be compilation configurable to the runtime. The wamr SDK tool "build_sdk.sh" supports menu config to select app components for building a customized runtime.
+
+A number of CMAKE variables are defined to control build of framework and components. You can create a cmake file for defining these variables and include it in the CMakeList.txt for your software, or pass it in "-x" argument when run the [build_sdk.sh](../../wamr-sdk/build_sdk.sh) for building the runtime SDK.
+
+```cmake
+set (WAMR_BUILD_APP_FRAMEWORK 1)
+set (WAMR_BUILD_APP_LIST WAMR_APP_BUILD_BASE)
+```
+
+Variables:
+
+- **WAMR_BUILD_APP_FRAMEWORK**: enable the application framework
+- **WAMR_BUILD_APP_LIST**: the selected components to be built into the final runtime
+
+
+
+The configuration file can be generated through the wamr-sdk menu config:
+
+```bash
+cd wamr-sdk
+./build_sdk -n [profile] -i
+```
+
+
+
+## Create new components
+
+Generally you should follow following steps to create a new component:
+
+- Copy the “template” for creating a new folder
+
+- Implement the app part
+
+  - If your component exports native function to WASM, ensure your created a header file under app for declaring the function prototype.
+  - If you component provides header files for the WASM applications to include, ensure it is placed under subfolder "wa_inc".
+
+- Implement the native part
+
+  - If your native function is exported to WASM, you need to create an inl file for the registration. It can be any file name, assuming the file name is "my_component.inl" here:
+
+    ```c
+    //use right signature for your functions
+    EXPORT_WASM_API_WITH_SIG(wasm_my_component_api_1, "(i*~)i"),
+    EXPORT_WASM_API_WITH_SIG(wasm_my_component_api_2, "(i)i"),
+    ```
+
+  - Ensure "wasm_lib.cmake" is provided as it will be included by the WAMR SDK building script
+
+  - Add a definition in "wasm_lib.cmake" for your component, e.g.
+
+    ```cmake
+    add_definitions (-DAPP_FRAMEWORK_MY_COMPONENT)
+    ```
+
+- Modify the file [app_ext_lib_export.c](./app_ext_lib_export.c) to register native APIs exported for the new introduced component. Skip it if not exporting native functions.
+
+  ```
+  #include "lib_export.h"
+
+  ...
+  #ifdef APP_FRAMEWORK_MY_COMPONENT // this definition is created in wasm_lib.cmake
+      #include "my_component_native_api.h"
+  #endif
+
+  static NativeSymbol extended_native_symbol_defs[] = {
+  ...
+  #ifdef APP_FRAMEWORK_MY_COMPONENT
+      #include "my_component.inl"
+  #endif
+  };
