+### Dataset Summary
+
+This is the concatenation of the datasets used to Pretrain RoBERTa.
+The dataset is not shuffled and contains raw text. It is packaged for convenicence.
+
+Essentially is the same as:
+```
+from datasets import load_dataset, concatenate_datasets
+bookcorpus = load_dataset("bookcorpus", split="train")
+openweb = load_dataset("openwebtext", split="train")
+cc_news = load_dataset("cc_news", split="train")
+cc_news = cc_news.remove_columns([col for col in cc_news.column_names if col != "text"])
+cc_stories = load_dataset("spacemanidol/cc-stories", split="train")
+return concatenate_datasets([bookcorpus, openweb, cc_news, cc_stories['train']])
+```
