+## Usage
+
+```python
+from datasets import load_dataset
+
+docs = load_dataset('irds/clueweb12_b13', 'docs')
+for record in docs:
+    record # {'doc_id': ..., 'url': ..., 'date': ..., 'http_headers': ..., 'body': ..., 'body_content_type': ...}
+
+```
+
+Note that calling `load_dataset` will download the dataset (or provide access instructions when it's not public) and make a copy of the
+data in 🤗 Dataset format.
