+## Building with `wasm-pack`
+
+To build the Rust code for WebAssembly and integrate it with the web frontend, follow these steps:
+
+1. **Install `wasm-pack`** (if you haven't already):
+
+```bash
+cargo install wasm-pack
+```
+
+2. **Build the Rust project for the web target**:
+
+```bash
+cd rust
+cargo install
+wasm-pack build --target web --out-dir ../web/pkg
+```
+
+This command compiles the Rust code to WebAssembly and outputs the generated files to the `../web/pkg` directory.
+
+3. **Start the web frontend** (if applicable):
+
+Navigate to the `web` directory and start your frontend development server as needed.
+
+```bash
+cd ../web
+# For example, if using npm:
+npm install
+npm run dev
+```
+
+Now you can experiment with the playground using the latest Rust-to-WebAssembly integration.
