+### Dataset Summary
+
+Extreme Summarization (XSum) Dataset.
+
+There are three features:
+  - document: Input news article.
+  - summary: One sentence summary of the article.
+  - id: BBC ID of the article.
+
+### Supported Tasks and Leaderboards
+
+[More Information Needed](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)

+### Data Instances
+
+#### default
+
+- **Size of downloaded dataset files:** 245.38 MB
+- **Size of the generated dataset:** 507.60 MB
+- **Total amount of disk used:** 752.98 MB
+
+An example of 'validation' looks as follows.
+```
+{
+    "document": "some-body",
+    "id": "29750031",
+    "summary": "some-sentence"
+}
+```
+
+### Data Fields
+
+The data fields are the same among all splits.
+
+#### default
+- `document`: a `string` feature.
+- `summary`: a `string` feature.
+- `id`: a `string` feature.
