+# mT5-base fine-tuned for News article Summarisation ✏️🧾
+
+[Google's mT5](https://aclanthology.org/2021.naacl-main.41/) for **summarisation** downstream task.
+
+# Model summary
+This repository contains a model for Danish abstractive summarisation of news articles. The summariser is based on a language-specific mT5-base. 
+
+The model is fine-tuned using an abstractive subset of the DaNewsroom dataset (Varab & Schluter, 2020), according to the binned density categories employed in Newsroom (Grusky et al., 2019).
