 This model is trained on the French-to-English portion of the [UN Corpus](https://conferences.unite.un.org/UNCorpus/),
 consisting of approx. 20 million segments.
 
+## Tokenizer
+
+The tokenizer was trained using [SentencePiece](https://github.com/google/sentencepiece) on shared vocabulary.
+Hence, there is only one SentencePiece model that can be used for tokenizing both the source and target texts.
