+# Set Total Records
+
+In some cases, we need to manually set the total records of our `Datatables` and skip its internal counting functionality.
+To achieve this, we can use `setTotalRecords($count)` api.
+
+```php
+use Datatables;
+
+Route::get('user-data', function() {
+	$model = App\User::query();
+
+	return Datatables::eloquent($model)
+				->setTotalRecords(100)
+				->make(true);
+});
+```
