-`nimbusml` provides battle-tested state-of-the-art ML algorithms,
-transforms and components, aiming to make them useful for all
-developers, data scientists, and information workers and helpful in all
-products, services and devices. The components are authored by the team
-members, as well as numerous contributors from MSR, CISL, Bing and other
-teams at Microsoft.
+`nimbusml` is a Python module that provides Python bindings for [ML.NET](https://github.com/dotnet/machinelearning).

+`nimbusml` aims to enable data science teams that are more familiar with Python
+to take advantage of ML.NET's functionality and performance. It provides
+battle-tested, state-of-the-art ML algorithms, transforms, and components. The
+components are authored by the team members, as well as numerous contributors
+from MSR, CISL, Bing, and other teams at Microsoft.
 
 `nimbusml` is interoperable with `scikit-learn` estimators and transforms,
-while adding a suite of highly optimized algorithms written in C++ and
-C\# for speed and performance. `nimbusml` trainers and transforms support
-the following data structures for the `fit()` and `transform()` methods:

 -   `numpy.ndarray`
 -   `scipy.sparse_cst`
 -   `pandas.DataFrame`.
 
-In addition, `nimbusml` also supports streaming from files without loading
-the dataset into memory, which allows training on data significantly
-exceeding memory using `FileDataStream`.

-With `FileDataStream` `nimbusml` is able to handle up to **billion** features
- and **billions** of training examples for select algorithms.
