 Context Provider Component used to switch the data module component rerendering
 between Sync and Async modes.
 
+_Usage_
+
+```js
+import { useSelect, AsyncModeProvider } from '@wordpress/data';
+
+function BlockCount() {
+  const count = useSelect( ( select ) => {
+    return select( 'core/block-editor' ).getBlockCount()
+  } );
+
+  return count;
+}
+
+function App() {
+  return (
+    <AsyncModeProvider value={ true }>
+      <BlockCount />
+    </AsyncModeProvider>
+  );
+}
+```
+
+In this example, the BlockCount component is rerendered asynchronously.
+It means if a more critical task is being performed (like typing in an input),
+the rerendering is delayed until the browser becomes IDLE.
+It is possible to nest multiple levels of AsyncModeProvider to fine-tune the rendering behavior.
+
 _Parameters_
 
 -   _props.value_ `boolean`: Enable Async Mode.
