 _DESCRIPTION = """\
-The Grocery Store Receipts Dataset is a collection of photos captured from various
-**grocery store receipts**. This dataset is specifically designed for tasks related to
-**Optical Character Recognition (OCR)** and is useful for retail.
-Each image in the dataset is accompanied by bounding box annotations, indicating the
-precise locations of specific text segments on the receipts. The text segments are
-categorized into four classes: **item, store, date_time and total**.
+The dataset consists of images of various grocery goods that have barcode labels.
+Each image in the dataset is annotated with polygons around the barcode labels.
+Additionally, Optical Character Recognition (**OCR**) has been performed on each
+bounding box to extract the barcode numbers.
+The dataset is particularly valuable for applications in *grocery retail, inventory
+management, supply chain optimization, and automated checkout systems*. It serves as a
+valuable resource for researchers, developers, and businesses working on barcode-related
+projects in the retail and logistics domains.
