 #### Scikit Learn
 
-Since [Scikit Learn](https://scikit-learn.org/stable/) 1.4, all transformers support Polars output.
-See the change log for
-[more details](https://scikit-learn.org/dev/whats_new/v1.4.html#changes-impacting-all-modules).
+The [Scikit Learn](https://scikit-learn.org/stable/) machine learning package accepts a Polars
+`DataFrame` as input/output to all transformers and as input to models.
+
+#### XGBoost & LightGBM
+
+XGBoost and LightGBM are gradient boosting packages for doing regression or classification on
+tabular data.
+[XGBoost accepts Polars `DataFrame` and `LazyFrame` as input](https://xgboost.readthedocs.io/en/latest/python/python_intro.html)

+#### Hugging Face
+
+Hugging Face is a platform for working with machine learning datasets and models.
+[Polars can be used to work with datasets downloaded from Hugging Face](io/hugging-face.md).
+
+#### Deep learning frameworks
+
+A `DataFrame` can be transformed
+[into a PyTorch format using `to_torch`](https://docs.pola.rs/api/python/stable/reference/dataframe/api/polars.DataFrame.to_torch.html)
+or
+[into a JAX format using `to_jax`](https://docs.pola.rs/api/python/stable/reference/dataframe/api/polars.DataFrame.to_jax.html).
