+### Dataset Summary
+
+From the original ICDAR2019 cTDaR [dataset](https://cndplab-founder.github.io/cTDaR2019/dataset-description.html) page:
+
+> _The dataset consists of modern documents and archival ones with various formats, including document images and born-digital formats such as PDF. The annotated contents contain the table entities and cell entities in a document, while we do not deal with nested tables._
+
+**This "resized" version contains all the images from "Track B," resized so that the largest dimension (either width or height) is 1000px. The annotations were converted from XML to JSON and boxes are represented in Pascal VOC format `(xmin, ymin, xmax, ymax)`. The original dataset did not contain "modern" tables or annotations, so the [supplement dataset](https://github.com/cndplab-founder/ICDAR2019_cTDaR_dataset_supplement) was merged into it, and its annotations converted accordingly.**
+
+## Dataset Structure
+
+### Data Instances
+
+A sample from the training set is provided below :
+```
+{
+    'image': <PIL.JpegImagePlugin.JpegImageFile image mode=L size=1000x729>,
+    'width': 1000,
+    'height': 729,
+    'category': 'historical',
+    'label': 0,
+    'bboxes_table': [[...]],
+    'bboxes_cell': [[...]]
+}
+```
+
+### Data Fields
+
+- `image`: A `PIL.Image.Image` object containing a document.
+- `width`: image's width.
+- `height`: image's height.
+- `category`: class label.
+- `label`: an `int` classification label.
+- `bboxes_table`: list of box coordinates in `(xmin, ymin, xmax, ymax)` format (Pascal VOC).
+- `bboxes_cell`: list of lists of box coordinates in `(xmin, ymin, xmax, ymax)` format (Pascal VOC) - the outer list matches the length of the `bboxes_table` list, and each of its elements is a list of cells.
