 ## Introduction
-ptt5-v2 models are pretrained T5 models tailored for the Portuguese language, continuing from Google's original checkpoints with sizes from t5-small to t5-3B.
+[ptt5-v2 models](https://huggingface.co/collections/unicamp-dl/ptt5-v2-666538a650188ba00aa8d2d0) are pretrained T5 models tailored for the Portuguese language, continuing from Google's original checkpoints with sizes from t5-small to t5-3B.
 For further information about the pretraining process and the complete study, please refer to our paper [PTT5: Pretraining and validating the T5 model on Brazilian Portuguese data](https://arxiv.org/abs/2008.09144).
