+1. install the required package
+    ``` bash
+    pip3 install django
+    ```
+
+2. Start device server
+    ``` bash
+    cd wasm_django/server
+    python3 wasm_server.py
+    ```
+
+3. Start IoT application management web portal
+    ``` bash
+    cd wasm_django
+    python3 manage.py runserver 0.0.0.0:80
+    ```
+
+## Start the runtime
+1. Download WAMR runtime from [help](http://localhost/help/) page
+    > NOTE: You need to start the server before accessing this link!
+
+2. Start a WAMR runtime from localhost
+    ``` bash
+    chmod +x simple
+    ./simple
+    ```
+    or from other computers
+    ``` bash

+# Component Test
+
+The purpose of this test suite is to verify the basic components of WAMR work well in combination. It is highly recommended to run pass all suites before each commitment.
+
+Prerequisites
+==============
+- clang is available to build wasm application.
+- python is installed to run test script.
+
+
+Run the test
+=============
+```
+start.py [-h] [-s SUITE_ID [SUITE_ID ...]] [-t CASE_ID [CASE_ID ...]]
+              [-n REPEAT_TIME] [--shuffle_all]
+              [--cases_list CASES_LIST_FILE_PATH] [--skip_proc]
+              [-b BINARIES] [-d] [--rebuild]
+```
+It builds out the simple project binary including WAMR runtime binary ```simple``` and the testing tool ```host_tool``` before running the test suites.
+
+Test output is like:
+```
+Test Execution Summary:
+        Success:              8
+        Cases fails:          0
+        Setup fails:          0
+        Case load fails:      0
+
+
+------------------------------------------------------------
+The run folder is [run-03-23-16-29]
+that's all. bye
+kill to quit..
+Killed
+```
+
+The detailed report and log is generated in ```run``` folder. The binaries copy is also put in that folder.
+
+Usage samples
+==============
+
+Run default test suite:
+</br>
+```python start.py```
+
+Rebuild all test apps and then run default test suite:
+</br>
+```python start.py --rebuild```
+
+Run a specified test suite:
+</br>
+```python start.py -s 01-life-cycle```
+
+Run a specified test case:
+</br>
+```python start.py -t 01-install```
+\ No newline at end of file

+# WAMR-IDE (Experimental)
+
+## Introduction
+
+The WAMR-IDE is an Integrated Development Environment to develop WebAssembly application with coding, compiling and source debugging support. It contains 3 components: `VSCode extension`, `wasm-toolchain docker image` and `wasm-debug-server docker image`.
+
+- `VSCode extension` is an `vscode` extension, with which user can build and manage projects, develop `wasm application`, including `building`, `running` and `debugging`.
+
+- `WASM-toolchain` is a docker image which provides building environment for wasm.
+
+- `WASM source debug server` is a docker image which provides running and source debugging environment for wasm application.
+
+---
+
+## How to setup WAMR IDE
+
+Now, we have same version tagged docker images, lldb binaries and VS Code installation file(.vsix file) packed for each GitHub release. So if you simply want to use WAMR debugging features in VS Code, the ideal(and effortless) way is following the tutorial in [this section](#21-download-wamr-vs-code-extension-from-the-github-releaserecommended-approach).
+
+Alternatively, if you want to build lldb, docker images, or .vsix file locally so that you can try the effect of your modification, you could refer to the tutorial in [this section](#22-build-wamr-vs-code-extension-locallyalternative-approach).
+
+### 1. Preparation
+
+#### 1.1. Install `VSCode` on host
+
+- make sure the version of [vscode](https://code.visualstudio.com/Download) you installed is at least _1.59.0_
+
+#### 1.2. Install `Docker` on host
+
+    1. [Windows: Docker Desktop](https://docs.docker.com/desktop/windows/install/)
+    2. [Ubuntu: Docker Engine](https://docs.docker.com/engine/install/ubuntu)
+       ```xml
+       OS requirements:
+       To install Docker Engine, you need the 64-bit version of one of these Ubuntu versions:
+       - Ubuntu Impish 21.10
+       - Ubuntu Hirsute 21.04
+       - Ubuntu Focal 20.04(LTS)
+       - Ubuntu Bionic 18.04(LTS)
+       ```
+
+### 2. WAMR VS Code extension: download from the GitHub release or build locally
+
+#### 2.1 Download WAMR VS Code extension from the GitHub release(Recommended approach)
+
+##### 2.1.1 Load docker images from the GitHub release tar file
+
+From now on, for each GitHub release, we have the same version tagged docker image saved as a tar file, which you can find and download in the GitHub release.
+
+You could download the tar archive files for docker images from the release, and then load them using the following commands:
+
+```sh
+# download the zip or tar.gz from release depending on your platform
+# decompress and get the tar file
+
+# on Linux/MacOS, you could use tar
+tar xf wasm-toolchain-{version number}.tar.gz
+tar xf wasm-debug-server-{version number}.tar.gz
+# or you could use unzip
+unzip wasm-toolchain-{version number}.zip
+unzip wasm-debug-server-{version number}.zip
+# load wasm-toolchain
+docker load --input wasm-toolchain.tar
+# load wasm-debug-server
+docker load --input wasm-debug-server.tar
+
+# on Windows, you could use any unzip software you like
+# then loading docker images using powershell or git bash
+# load wasm-toolchain
+docker load --input ./wasm-toolchain.tar
+# load wasm-debug-server
+docker load --input ./wasm-debug-server.tar
+```
+
+##### 2.1.2 Download the VS Code extension installation file from the GitHub release
+
+From now on, for each GitHub release, we have the same version tagged zip/tar.gz file. For example, in release version 1.1.2, you can easily download and decompress `wamr-ide-1.1.2.tar.gz` `wamr-ide-1.1.2.zip`, which contains `wamr-ide.vsix` VS Code extension installation file. As you can imagine, in the future, when new releases are available, you can freely choose whichever version(for example, 1.2.0, 1.3.0, etc.) you prefer. It should work as long as you download the same version tagged docker image and .vsix file.
+
+##### 2.1.3 Install extension from vsix
+
+![install_from_vsix](./Media/install_from_vsix.png "install wamr-ide from vsix")
+
+select `wamr-ide.vsix` which you have decompressed from `.tar.gz` or `.zip` file.
+
+#### 2.2 Build WAMR VS Code extension locally(Alternative approach)
+
+You could also build the VS Code extension locally, the following instruction provides a thorough tutorial. It's worth noting that in the local build tutorial we use hard-coded tag version 1.0 other than the semantic version of WAMR.
+
+Note: Please ensure that the scripts under `resource` directories have execution permission. While on git they have x bits, you might have dropped them eg. by copying them from Windows. Similarly, do not drop execution permission when copying `lldb` binaries under `resource/debug/bin`.
+
+##### 2.2.1 Build docker images on host
+
+We have 2 docker images which should be built or loaded on your host, `wasm-toolchain` and `wasm-debug-server`. To build these 2 images, please enter the `WASM-Debug-Server/Docker` & `WASM-Toolchain/Docker`, then execute the `build_docker_image` script respectively.
+
+Windows (powershell):
+
+```batch
+$ cd .\WASM-Toolchain\Docker
+$ .\build_docker_image.bat
+$ cd .\WASM-Debug-Server\Docker
+$ .\build_docker_image.bat
+```
+
+Linux:
+
+```shell
+$ cd ./WASM-Toolchain/Docker
+$ ./build_docker_image.sh
+$ cd ./WASM-Debug-Server/Docker
+$ ./build_docker_image.sh
+```
+
+##### 2.2.2 After building, you can find `wasm-toolchain` and `wasm-debug-server` docker images on your local
+
+![docker-images](./Media/docker_images.png)
+
+##### 2.2.3 If building docker images fail during the process
+
+Sometimes building the Docker images may fail due to bad network conditions. If the `wasm-toolchain` and `wasm-debug-server` images do not exist after building, please build them manually. Fix the proxy setting if needed and execute the following command to build docker images.
+
+![docker-engine-config](./Media/docker_config.jpg)
+
+> Note: please correctly replace example proxy address with your own before you run manually.
+
+```xml
+$ cd .\docker_images\wasm-debug-server
+$ docker build --no-cache --build-arg http_proxy=http://proxy.example.com:1234
+--build-arg https_proxy=http://proxy.example.com:1234 -t wasm-debug-server:1.0 .
+```
+
+```xml
+$ cd .\docker_images\wasm-toolchain
+$ docker build --no-cache --build-arg http_proxy=http://proxy.example.com:1234
+--build-arg https_proxy=http://proxy.example.com:1234 -t wasm-toolchain:1.0 .
+```
+
+##### 2.2.4 If you encounter the problem `failed to solve with frontend dockerfile.v0: failed to create LLB definition`, please config your docker desktop
+
+![docker-engine-config](./Media/docker_engine_config.png)
+
+##### 2.2.5 Points To Remember
+
+- Make sure that the `wasm-toolchain:1.0` and `wasm-debug-server:1.0` docker images are both successfully built before using `WAMR IDE`, otherwise `Build`, `Run` and `Debug` will not work.
+
+##### 2.2.6 Generate wamride extension package file
+
+`wamride-1.0.0.vsix` can be packaged by [`npm vsce`](https://code.visualstudio.com/api/working-with-extensions/publishing-extension).
+
+```shell
+$ npm install -g vsce
+$ cd VSCode-Extension
+$ rm -rf node_modules
+$ npm install
+$ vsce package
+```
+
+##### 2.2.7 Enable VS Code debugging feature
+
+By default, when you build .vsix locally, the debugging feature is off. Suppose you want to enable the source debugging feature. In that case, you could download `lldb` binaries from our GitHub release (for example, `wamr-lldb-1.1.2-x86_64-ubuntu-20.04.tar.gz`), decompress and put every subdirectory and file to the installed directory of your VS Code extension.
+
+For example, let's say you are on an Ubuntu 20.04 machine. You first download and decompress `wamr-lldb-1.1.2-x86_64-ubuntu-20.04.tar.gz`, and you will get a `wamr-lldb` folder (or `inst` folder in our earlier release). Then, you can simply copy the files and directory inside that folder to the relative path `resource/debug/linux/` under your VS Code extension installation directory.
+
+Example commands on an Ubuntu 20.04 machine:
+
+```shell
+# decompress .tar.gz file and get the folder
+$ ls wamr-lldb
+bin  lib  package.json  syntaxes
+# copy everything to the vscode extension installation path(in this case, it's /home/{usrname}/.vscode-server/extensions/wamr.wamride-1.0.0/)
+$ cp inst/* /home/{usrname}/.vscode-server/extensions/wamr.wamride-1.0.0/resource/debug/linux/
+```
+
+If you want to use your own patched `lldb`, you could follow this [instruction](../../doc/source_debugging.md#debugging-with-interpreter) to build `lldb`. And follow this [instruction](./VSCode-Extension/resource/debug/README.md)
+to copy the binaries to replace the existing ones.
+
+
+> **You can also debug the extension directly follow this [instruction](./VSCode-Extension/README.md) without packing the extension.**
+
+##### 2.2.7 Install extension from vsix
+
+![install_from_vsix](./Media/install_from_vsix.png "install wamr-ide from vsix")
+
+select `wamride-1.0.0.vsix` which you have packed on your host.
+
+---
+
+## How to use `wamr-ide`
+
+#### `WAMR-IDE` extension contains 2 components as following picture showing. `WAMR IDE` for workspace and project management and `Current Project` for project's execution.
+
+![wamr_ide_main_menu](./Media/wamr_ide_main_menu.png "wamr-ide main menu")
+
+### Project Execution
+
+#### 1. New project
+
+When you click `New project` button, the extension will pop up a message box at the bottom right of the screen as following:
+
+![set-up-workspace-message](./Media/set_up_workspace_message.png "set up workspace message box")
+
+You can click `Set up now` and select the target folder to create project workspace, or you click `Maybe later` to close the message box.
+
+> Note that your selected workspace folder should be **empty** or the folder you have set up as workspace.
+
+After setting up workspace, extension will prompt successful message:
+
+```xml
+Workspace has been set up successfully!
+```
+
+Then click `New project` button again, a new page will show as following.
+
+![new-project-page](./Media/new_project_page.png "new project page")
+
+Enter the `Project name` and select the `Template`, then click `Create` button. A new project will be generated and opened in your current `VS Code window` or in a new `VS Code window`.
+
+> Opening in current windows or a new one depends on whether your `vscode's explorer` is empty or not. If empty, open in current window, or open in the new vscode window.
+
+A new initialized project is as following picture shows.
+
+![project-template](./Media/project_template.png "default project template")
+
+`.wamr` is the project configuration folder which contains 3 files, `CMakeLists.txt`, `project.cmake`, and `compilation_config.json`. `CMakeLists.txt` is used to build `wasm target` and the `project.cmake` is included in `CMakeLists.txt`. `compilation_config.json` includes the user's customized configuration such as folders which should be added in the include path.
+
+#### 2. Open project
+
+Click `Open project` button, `quick-pick-box` will show as following. All projects under your current workspace will be shown and can be selected.
+
+![configuration file](./Media/open_project_page.png "configuration file")
+
+#### 3. Change workspace
+
+Click `Change workspace` button, a dialog will show as following. You can select 1 folder in file system as workspace, and the new workspace path will override previous workspace, and all new created projects will be generated in the new workspace.
+
+![change workspace ](./Media/change_workspace_dialog.png "change workspace dialog")
+
+#### 4. Customize `include paths` and `exclude source files`
+
+    Extension supports adding header file folder to `include path` and excluding source file from build.
+
+- `Add to include path`
+
+  - Move the cursor to the `folder` and right click, then `menus` will be shown as following. Click `Toggle state of path including`.
+
+  ![right click menus](./Media/right_click_menus_1.png "right click menus")
+
+- `Exclude source file from build`
+
+  - Move the cursor to the `source file` and right click, then `menus` will be shown as following. Click `Toggle state of excluding`.
+
+  ![right click menus](./Media/right_click_menus_2.png "right click menus")
+
+#### After setting up `include path` and `exclude files`, the corresponding folder and files will be decorated with color and icon as following picture shows
+
+  ![decoration for files](./Media/decoration_for_files.png "decoration for files")
+
+  At the same time, all added `include path` and `exclude files` will be saved in `.wamr/compilation_config.json` as json array.
+
+  ![compilation config](./Media/compilation_config_2.png "compilation config")
+
+> `Toggle state of path including` just shows when selecting `folder` and hides with other resources.
+>
+> `Toggle state of excluding` just shows when selecting `[.c | .cpp | .cxx] source files` and hides with other resources.
+
+### Current Project Management
+
+#### 1. Configuration
+
+Click `Configuration` button, a new page will be shown as following. You can config building target with `Include paths`, `Initial & Max linear memory`, `stack size`, `exported_symbols` and `include paths`, `exclude files`.
+
+![config building target](./Media/Config_building_target.png "config building target")
+
+Then click `Modify` button to confirm, if configurations are modified successfully and following message will pop. Click `OK`, the page will be auto closed.
+
+![save configuration](./Media/save_configuration.png "save configuration")
+
+And all configuration will be saved in `.wamr/compilation_config.json`.
+
+![configuration file](./Media/compilation_config.png "configuration file")
+
+#### 2. `Build`
+
+When you have completed coding and ready to build target, click `build` button and the `wasm-toolchain` will auto start a container and execute the building process.
+
+![build terminal output](./Media/build_terminal.png "build terminal output")
+
+After successful building execution, `build` folder will be generated in `explorer`, in which `${output_file_name}.wasm` is exist.
+
+![build folder](./Media/build_folder.png "build folder")
+
+> Note that to start `docker service` firstly.
+
+#### 3. Run
+
+Click `Run` button and `wasm-debug-server` docker image will auto start a container and execute the running process.
+
+![run](./Media/run.png "run wasm")
+
+#### 4. Debug
+
+Click `Debug` button will trigger start ip `wamr-debug-server` docker image, and boot up `lldb debug server` inside of iwasm. Then start a debugging session with configuration to connect. Tap `F11` or click `step into` to start debugging.
+
+![debug](./Media/debug.png "source debugging")
+
+> Docker containers will be auto stopped and removed after the execution.

+# CONTRIBUTING
+
+## Pull requests
+
+To submit your change:
+
+-   Make sure your code is in line with our
+    [coding conventions](##Coding-conventions).
+-   Create an [issue] describing the bug the PR fixes or the feature you intend
+    to implement.
+-   Submit a [pull request] into the main branch.
+
+## Coding conventions
+
+#### Format
+
+The codebase is formatted by `Prettier` and the `.prettierrc.json` has been
+configured.
+
+-   VSCode along with `Format on Save` configuration could easily format your
+    code during development.
+-   You can run `prettier-format-check` and `prettier-format-apply` to check and
+    format your codebase with `prettier` in terminal.
+
+#### Lint
+
+`ESlint` is used as linter for the codebase and the `.eslintrc.json` has been
+configured.
+
+-   It's suggested to run `npm run lint` then fix errors and warnings before
+    committing.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# Introduction
+
+### An integrated development environment for WASM.
+
+# How to debug this extension
+> Note that when you download and
+> decompress to get .vsix file from [our release](https://github.com/bytecodealliance/wasm-micro-runtime/releases).
+> It's by default that the `source debugging` feature is not enabled.
+> If you want to enable the `source debugging` feature of this extension,
+> you could  download `lldb` from [our release](https://github.com/bytecodealliance/wasm-micro-runtime/releases)
+> (This is the recommended way, and you could do it with a single click in VS Code).
+> Then if you want to use your customized lldb patch,
+> you could build your own version of `lldb`
+> and then follow this [instruction](./resource/debug/README.md)
+> to put them in the correct path
+
+### 1. open `VSCode_Extension` directory with the `vscode`
+
+```xml
+File -> Open Folder -> select `VSCode_Extension`
+```
+
+### 2. run `npm install` in `terminal` to install necessary dependencies.
+
+### 3. click `F5` or `ctrl+shift+D` switch to `Run and Debug` panel and click `Run Extension` to boot.
+
+# Code Format
+
+`prettier` is recommended and `.prettierrc.json` has been provided in workspace.
+More details and usage guidance please refer [prettier](https://prettier.io/docs/en/install.html)
+
+You can run following commands in current extension directory to check and apply
+```shell
+# install prettier firstly
+npm install --save-dev prettier
+# check format
+npm run prettier-format-check
+# apply
+npm run prettier-format-apply
+```

+### If you want to enable `source debugging` for this extension and use your own patched `lldb`, please build `lldb` firstly following this [instruction](../../../../../doc/source_debugging.md#debugging-with-interpreter)
+
+### After building(`linux` for example), create `bin` folder and `lib` folder respectively in `linux` directory, add following necessary target files into the folders
+
+```shell
+/llvm/build-lldb/bin/lldb # move this file to {VS Code directory}/resource/debug/linux/bin/
+/llvm/build-lldb/bin/lldb-vscode # move this file to {VS Code directory}/resource/debug/linux/bin/
+/llvm/build-lldb/lib/liblldb.so.13 # move this file to {VS Code directory}/resource/debug/linux/lib/
+```
+
+> If you are debugging this extension following this [tutorial](../../README.md), {VS Code directory} will be `{WAMR root directory}/test-tools/wamr-ide/VSCode-Extension`. If you want to replace the current lldb with your own patched version so that you can use your patched lldb in VS Code, {VS Code directory} will be `~/.vscode/extensions/wamr.wamride-1.1.2` or `~/.vscode-server/extensions/wamr.wamride-1.1.2`.
+
+Note: For macOS, the library is named like `liblldb.13.0.1.dylib`.
+
+### Then you can start the extension and run the execute source debugging by clicking the `debug` button in the extension panel.

+### Build Docker Image
+
+-   Linux
+
+    ```shell
+    ./build_docker_image.sh
+    ```
+
+-   Windows
+
+    ```shell
+    ./build_docker_image.bat
+    ```
+
+
+### Resource Details
+
+-   `Dockerflie` is the source file to build `wasm-debug-server` docker image
+-   `resource/debug.sh` is the script to execute the wasm app in debug mod, will start up the debugger server inside of the `iwasm` and hold to wait for connecting.
+-   `resource/run.sh` is the script to execute the wasm app directly.
