 # WASM API
 
-The KCL core is written by Rust and can be compiled to the `wasm-wasi` target using toolchains such as cargo. With the help of WASM, we can also easily achieve multilingual and browser integration. Here is how we can use the KCL WASM module in Node.js, Go and Rust.
+The KCL core is written by Rust and can be compiled to the `wasm-wasi` target using toolchains such as cargo. With the help of WASM, we can also easily achieve multilingual and browser integration. Here is how we can use the KCL WASM module in Browser, Node.js, Go and Rust.
 
 ## Quick Start
 
 We can find and download KCL WASM module from [here](https://github.com/kcl-lang/lib/tree/main/wasm)
 
+## Browser
+
+Install the dependency
+
+```shell
+npm install buffer @wasmer/wasi @kcl-lang/wasm-lib
+```
+
+> Note: buffer is required by @wasmer/wasi.
+
+Write the code
+
+```typescript
+import { load, invokeKCLRun } from "@kcl-lang/wasm-lib";
+
+async function main() {
+  const inst = await load();
+  const result = invokeKCLRun(inst, {
+    filename: "test.k",
+    source: `
+schema Person:
+  name: str
+
+p = Person {name = "Alice"}`,
+  });
+  console.log(result);
+}
+
+main();
+```
+
+Here, we use `webpack` to bundle the website, the `webpack.config.js` config as follows.
+
+> Note: This configuration includes necessary settings for @wasmer/wasi and other required plugins.
+
+```js
+const HtmlWebpackPlugin = require("html-webpack-plugin");
+const MiniCssExtractPlugin = require("mini-css-extract-plugin");
+const path = require("path");
+const webpack = require("webpack");
+
+const dist = path.resolve("./dist");
+const isProduction = process.argv.some((x) => x === "--mode=production");
+const hash = isProduction ? ".[contenthash]" : "";
+
+module.exports = {
+  mode: "development",
+  entry: {
+    main: "./src/main.ts",
+  },

+        },
+      },
+    ],
+  },
+  plugins: [
+    new MiniCssExtractPlugin(),
+    new HtmlWebpackPlugin({
+      template: path.resolve(__dirname, "./src/index.html"),
+    }),
+    new webpack.IgnorePlugin({
+      resourceRegExp: /^(path|ws|crypto|fs|os|util|node-fetch)$/,
+    }),
+    // needed by @wasmer/wasi
+    new webpack.ProvidePlugin({

+    fallback: {
+      // needed by @wasmer/wasi
+      buffer: require.resolve("buffer/"),
+    },
+  },
+};
+```

+
+If you encounter any issues, make sure:
+
+- All dependencies are correctly installed.
+- Your `webpack.config.js` is properly set up.

 # WASM API
 
-KCL 核心用 Rust 编写，可以使用 cargo 等工具链编译到 `wasm-wasi` 目标。在 WASM 的帮助下，也可以轻松实现多语言和浏览器集成。以下是在 Node.js 环境, Go 和 Rust 中使用 KCL WASM 模块的方法。
+KCL 核心用 Rust 编写，可以使用 cargo 等工具链编译到 `wasm-wasi` 目标。在 WASM 的帮助下，也可以轻松实现多语言和浏览器集成。以下是在浏览器, Node.js 环境, Go 和 Rust 中使用 KCL WASM 模块的方法。
 
 ## 快速开始
 
 可以从[这里](https://github.com/kcl-lang/lib/tree/main/wasm)找到 KCL WASM 模块。
 
+## 浏览器环境
+
+安装依赖
+
+```shell
+npm install buffer @wasmer/wasi @kcl-lang/wasm-lib
+```
+
+> 注意：buffer 是 @wasmer/wasi 所需的依赖。
+
+编写代码
+
+```ts
+import { load, invokeKCLRun } from "@kcl-lang/wasm-lib";
+
+async function main() {
+  const inst = await load();
+  const result = invokeKCLRun(inst, {
+    filename: "test.k",
+    source: `
+schema Person:
+  name: str
+p = Person {name = "Alice"}`,
+  });
+  console.log(result);
+}
+
+main();
+```
+
+在这里，我们使用 `webpack` 来打包网站, `webpack.config.js` 的配置如下。
+
+> 注意：此配置包含了 @wasmer/wasi 所需的必要设置和其他必需的插件。
