+#### Using Breadcrumbs in Some Other Way
+
+If you need to use the breadcrumbs in some other way—maybe for rending via a client-side
+framework that Gretel doesn’t already integrate with—you can always just get the current
+breadcrumbs as a `Collection` or `array` off the route:
+
+```php
+Route::breadcrumbs()->toCollection();  // Collection of `Breadcrumb` objects
+Route::breadcrumbs()->toArray();       // Array of `Breadcrumb` objects
+Route::breadcrumbs()->jsonSerialize(); // Array of breadcrumb arrays (title, url, is_current_page)
+Route::breadcrumbs()->toJson();        // JSON string of breadcrumbs matching jsonSerialize
+```
+
+For example, our [Inertia.js integration](#integration-with-third-party-packages) could
+easily be implemented as:
+
+```php
+Inertia::share('breadcrumbs', function(Request $request) {
+    return $request->route()->breadcrumbs()->jsonSerialize();
+});
+```
