+## Expected Outcome
+
+It should work with index routes inside the children routes
+
+## Scenario
+
+- no recursion
+  ```ts
+  export function addRoutesToAllRoutes(routes: RouteObject[]): void {
+    console.log('routes to add to allRoutes::', JSON.stringify(routes));
+    routes.forEach(route => {
+      if (!allRoutes.has(route)) {
+        allRoutes.add(route);
+      }
+    });
+  }
+  ```
+- with index route
+  ```ts
+    {
+    path: '/post/:post',
+    element: <div>Post</div>,
+    children: [
+      { index: true, element: <div>Post Index</div> },
+      { path: '/post/:post/related', element: <div>Related Posts</div> },

-## Expected Outcome
-
-It should work with index routes inside the children routes
-
-## Scenario
-
-- no recursion
-  ```ts
-  export function addRoutesToAllRoutes(routes: RouteObject[]): void {
-    console.log('routes to add to allRoutes::', JSON.stringify(routes));
-    routes.forEach(route => {
-      if (!allRoutes.has(route)) {
-        allRoutes.add(route);
-      }
-    });
-  }
-  ```
-- no index route
-  ```ts
-    {
-    path: '/post/:post',
-    element: <div>Post</div>,
-    children: [
-     //  { index: true, element: <div>Post Index</div> },
-      { path: '/post/:post/related', element: <div>Related Posts</div> },

-## Expected Outcome
-
-It should work with index routes inside the children routes
-
-## Scenario
-
-- no recursion
-  ```ts
-  export function addRoutesToAllRoutes(routes: RouteObject[]): void {
-    console.log('routes to add to allRoutes::', JSON.stringify(routes));
-    routes.forEach(route => {
-      if (!allRoutes.has(route)) {
-        allRoutes.add(route);
-      }
-    });
-  }
-  ```
-- with index route
-  ```ts
-    {
-    path: '/post/:post',
-    element: <div>Post</div>,
-    children: [
-      { index: true, element: <div>Post Index</div> },
-      { path: '/post/:post/related', element: <div>Related Posts</div> },
