+# RecursionProvider
+
+According to Gutenberg's block rendering architecture, any block type capable of recursion should be responsible for handling its own infinite loops. 
+
+To help with detecting infinite loops on the client, the `RecursionProvider` component and the `useHasRecursion()` hook are used to identify if a block has already been rendered. 
+
+## Usage
+
+```jsx
+/**
+ * WordPress dependencies
+ */
+import {
+	__experimentalRecursionProvider as RecursionProvider,
+	__experimentalUseHasRecursion as useHasRecursion,
+	useBlockProps,
+	Warning,
+} from '@wordpress/block-editor';
+import { __ } from '@wordpress/i18n';
+
+export default function MyRecursiveBlockEdit( { attributes: { ref } } ) {
+	const hasAlreadyRendered = useHasRecursion( ref );
+	const blockProps = useBlockProps( {
+		className: 'my-block__custom-class',
+	} );
+
+	if ( hasAlreadyRendered ) {
+		return (
+			<div { ...blockProps }>
+				<Warning>
+					{ __( 'Block cannot be rendered inside itself.' ) }
+				</Warning>
+			</div>
+		);
+	}
+
+	return (
+		<RecursionProvider uniqueId={ ref }>
+			Block editing code here....
+		</RecursionProvider>
+	);
+}
+
+/// ...
+
+<MyRecursiveBlockEdit />;
+```
