+## Adding a heading row
+
+A heading row can easily be added by adding the `WithHeadings` concern. The heading row will be added
+as very first row of the sheet.
+
+```php
+
+use Maatwebsite\Excel\Concerns\FromQuery;
+use Maatwebsite\Excel\Concerns\WithHeadings;
+
+class InvoicesExport implements FromQuery, WithHeadings
+{
+    public function headings(): array
+    {
+        return [
+            '#',
+            'User',
+            'Date',
+        ];
+    }
+}
+```
+
+If you need to have multiple heading rows, you can return multiple rows from the `headings()` method:
+
+
+```php
+
+use Maatwebsite\Excel\Concerns\FromQuery;
+use Maatwebsite\Excel\Concerns\WithHeadings;
+
+class InvoicesExport implements FromQuery, WithHeadings
+{
+    public function headings(): array

+           ['Second row', 'Second row'],
+        ];
+    }

 ## Prepare rows
 
 If you need to prepare rows before appending these rows to sheet, you can add method `prepareRows` to your export class. This method will be called before flattening the query output and calling `map()`.
