+
+## Model description
+
+The REALM checkpoint pretrained with CC-News as target corpus and Wikipedia as knowledge corpus, converted from the TF checkpoint provided by Google Language.
+
+The original paper, code, and checkpoints can be found [here](https://github.com/google-research/language/tree/master/language/realm).
+
+## Usage
+
+```python
+from transformers import RealmForOpenQA
+
+openqa = RealmForOpenQA.from_pretrained("qqaatw/realm-cc-news-pretrained-openqa")
+```
