+# Bert-small2Bert-small Summarization with 🤗EncoderDecoder Framework
+
+This model is a warm-started *BERT2BERT* ([small](https://huggingface.co/google/bert_uncased_L-4_H-512_A-8)) model fine-tuned on the *CNN/Dailymail* summarization dataset.
+
+The model achieves a **17.37** ROUGE-2 score on *CNN/Dailymail*'s test dataset.
+
+For more details on how the model was fine-tuned, please refer to 
+[this](https://colab.research.google.com/drive/1Ekd5pUeCX7VOrMx94_czTkwNtLN32Uyu?usp=sharing) notebook.
