+# BERTje: A Dutch BERT model
+
+BERTje is a Dutch pre-trained BERT model developed at the University of Groningen.
+
+⚠️ **The new home of this model is the [GroNLP](https://huggingface.co/GroNLP) organization.**
+
+BERTje now lives at: [`GroNLP/bert-base-dutch-cased`](https://huggingface.co/GroNLP/bert-base-dutch-cased)
+
+The model weights of the versions at `wietsedv/` and `GroNLP/` are the same, so do not worry if you use(d) `wietsedv/bert-base-dutch-cased`.
