+# Dataset Card for `istella22`
+
+The `istella22` dataset, provided by the [ir-datasets](https://ir-datasets.com/) package.
+For more information about the dataset, see the [documentation](https://ir-datasets.com/istella22#istella22).
+
+# Data
+
+This dataset provides:
+ - `docs` (documents, i.e., the corpus); count=8,421,456
+
+
+This dataset is used by: [`istella22_test`](https://huggingface.co/datasets/irds/istella22_test), [`istella22_test_fold1`](https://huggingface.co/datasets/irds/istella22_test_fold1), [`istella22_test_fold2`](https://huggingface.co/datasets/irds/istella22_test_fold2), [`istella22_test_fold3`](https://huggingface.co/datasets/irds/istella22_test_fold3), [`istella22_test_fold4`](https://huggingface.co/datasets/irds/istella22_test_fold4), [`istella22_test_fold5`](https://huggingface.co/datasets/irds/istella22_test_fold5)
+
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+docs = load_dataset('irds/istella22', 'docs')
+for record in docs:
+    record # {'doc_id': ..., 'title': ..., 'url': ..., 'text': ..., 'extra_text': ..., 'lang': ..., 'lang_pct': ...}
+
+```
+
+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.
