+# WASM for Cedarling
+
+Cedarling provides a binding for JavaScript programs via the `wasm-pack` tool. This allows browser developers to use the cedarling crate in their code directly.
+
+## Requirements
+
+- Rust 1.63 or greater
+- Installed `wasm-pack` via `cargo`
+- clang with `wasm` target support
+
+## Building
+
+- Install `wasm-pack` by:
+
+  ```sh
+  cargo install wasm-pack
+  ```
+
+- Build cedarling `wasm` in release:
+
+  ```bash
+  wasm-pack build --release --target web
+  ```
+
+  `wasm-pack` automatically make optimization of `wasm` binary file, using `wasm-opt`.
+- Get result in the `pkg` folder.
+
+## Including in projects
+
+For using result files in browser project you need make result `pkg` folder accessible for loading in the browser so that you can later import the corresponding file from the browser.
+
+Here is example of code snippet:
+
+```html
+   <script type="module">
+        import initWasm, { init } from "/pkg/cedarling_wasm.js";
+
+        async function main() {
+            await initWasm(); // Initialize the WebAssembly module
+
+            // init cedarling with `BOOTSTRAP` config
+            let instance = await init({
+               "CEDARLING_APPLICATION_NAME": "My App",
+                "CEDARLING_POLICY_STORE_URI": "https://example.com/policy-store.json",

+            });
+            // make authorize request
+            let result = await instance.authorize({
+                "tokens": {
+                    "access_token": "...",

+## Usage
+
+Before usage make sure that you have completed `Building` steps.
+You can find usage examples in the following locations:
+
+- `jans-cedarling/bindings/cedarling_wasm/index.html`: A simple example demonstrating basic usage.
+- `jans-cedarling/bindings/cedarling_wasm/cedarling_app.html`: A fully featured `Cedarling` browser app where you can test and validate your configuration.
