## Contributing to KerasNLP

Patches to KerasNLP are welcome!

The source-of-truth repository lives under
[TF Model Garden NLP](https://github.com/tensorflow/models/tree/master/official/nlp/keras_nlp),
and is mirrored as a read-only repository under
[keras-team/keras-nlp](https://github.com/keras-team/keras-nlp).
Contributions should be made as PRs to the TF Model Garden repository.
This is to ensure the codebase is rigorously tested with state-of-art models
on different accelerators.
In the long run, we will move development to the current repository `keras-team/keras-nlp`.
