-If you're using `Vite`, you should add the following to your vite.config.ts:
+### Vite
+
+#### Vite 8.1 and newer
+
+[Vite 8.1 introduced built-in WebAssembly ESM integration](https://vite.dev/blog/announcing-vite8-1#wasm-esm-integration-support),
+so `vite-plugin-wasm` is no longer needed. The default browser targets also
+support top-level `await` (TLA), so `vite-plugin-top-level-await` is not needed.
+You can import from `loro-crdt` directly.
+
+If you customize `build.target`, use browser targets that support TLA. Changing
+the target does not add TLA support to older browsers. See
+[Vite's WebAssembly guide](https://vite.dev/guide/features#webassembly).
+
+**Development workaround (Vite 8.1.0 with Loro 1.16.4):** This combination can
+fail during WASM initialization with `Cannot read properties of undefined
+(reading 'memory')` when Loro is pre-bundled. If you encounter this error,
+exclude Loro from dependency pre-bundling:
 
 ```ts no-run
+import { defineConfig } from "vite";
+
+export default defineConfig({
+  optimizeDeps: {
+    exclude: ["loro-crdt"],
+  },
+});
+```
+
+Merge this setting into your existing config. It affects development only;
+production builds still bundle Loro normally.
+
+#### Older Vite versions
+
+For Vite versions before 8.1, install the plugins:
+
+```bash
+npm install -D vite-plugin-wasm vite-plugin-top-level-await
+```
+
+Add them alongside your existing framework plugins in `vite.config.ts`:
+
+```ts no-run
+import { defineConfig } from "vite";
 import wasm from "vite-plugin-wasm";
 import topLevelAwait from "vite-plugin-top-level-await";
 
 export default defineConfig({
-  plugins: [...otherConfigures, wasm(), topLevelAwait()],
+  plugins: [wasm(), topLevelAwait()],
 });
 ```
 
+For targets with native TLA support, the TLA plugin can be omitted; see the
+[plugin's usage guide](https://github.com/Menci/vite-plugin-wasm#usage) for target
+configuration and compatibility details.
