+###  Adding Notes
+
+Notes are old style comments in Excel (notes on a light yellow background). You can add notes to any cells
+
+```php
+
+$sheet->writeCell('Text to A1');
+$sheet->addNote('A1', 'This is a note for cell A1');
+
+$sheet->writeCell('Text to B1')->addNote('This is a note for B1');
+$sheet->writeTo('C4', 'Text to C4')->addNote('Note for C1');
+
+
+$sheet->addNote('E4:F8', 'This note will added to E4');
+
+```
