 # Northern Frisian translation model
 This is an [NLLB-200-600M](https://huggingface.co/facebook/nllb-200-distilled-600M) model fine-tuned for translating between German and 
-the Northern Frisian dialects of Mooringer Frasch and Wiringhiirder Freesk following [this great blogpost](https://cointegrated.medium.com/a37fc706b865).

+While the additional data introduced with the new dialect has improved the model's performance for translations German <-> Mooring 
+compared to [nllb-deu-moo](https://huggingface.co/CmdCody/nllb-deu-moo), the extended training has at the same time degraded 
+the performance for other languages. For example, translating English to Mooring still works relatively well while conversely translating 
+Mooring to English does not.
