+### Dataset Summary
+
+The WSDMCup2023 Dataset consists of images associated with textual questions.
+One entry (instance) in our dataset is a question-image pair labeled with the ground truth coordinates of a bounding box containing
+the visual answer to the given question. The images were obtained from a CC BY-licensed subset of the Microsoft Common Objects in
+Context dataset, [MS COCO](https://cocodataset.org/). All data labeling was performed on the [Toloka crowdsourcing platform](https://toloka.ai/).
+
+The dataset has 45,199 instances split among three subsets: train (38,990 instances), public test (1,705 instances),
+and private test (4,504 instances). The entire train dataset will be available for everyone from the start of the challenge.
+The public test dataset will be available during the evaluation phase of the competition but without any ground truth labels.
+The private test dataset will not be available until the challenge ends.
