 - For feeding user/item features to model just specify dataframes when constructing `Dataset`. [Check our tutorial](examples/4_dataset_with_features.ipynb)
 - For warm / cold inference just provide all required ids in `users` or `target_items` parameters of `recommend` or `recommend_to_items` methods and make sure you have features in the dataset for warm users/items. **Nothing else is needed, everything works out of the box.**
