+## Using build plugin
 
-```js
-// ESM
-import {} from "unwasm";
+###### Rollup
 
-// CommonJS
-const {} = await import("unwasm")
+```js
+import unwasmPlugin from "unwasm/plugin";
+
+export default {
+  plugins: [
+    unwasmPlugin.rollup({
+      /* options */
+    }),
+  ],

 ```
 
+### Options
+
+- `esmImport`: Direct import the wasm file instead of bundling, required in Cloudflare Workers (default is `false`)
+- `lazy`: Import `.wasm` files using a lazily evaluated promise for compatibility with runtimes without top-level await support (default is `false`)
