+Ecosystem
+=========
+
+There is a constantly growing number of users and packages using pandas
+to address their specific needs in data preparation, analysis and visualization.
+pandas is being used ubiquitously and is a good choise to handle small-sized data.
+However, pandas scales poorly and is non-interactive on moderate to large datasets.
+Modin provides a drop-in replacement API for pandas and scales computation across nodes and
+CPUs available. What you need to do to switch to Modin is just replace a single line of code.
+
+.. code-block:: python
+
+    # import pandas as pd
+    import modin.pandas as pd
+
+While most packages can consume a pandas DataFrame and operate it efficiently,
+this is not the case with a Modin DataFrame due to its distributed nature.
+Thus, some packages may lack support for handling Modin DataFrame(s) correctly and,
+moreover, efficiently. Modin implements such methods as ``__array__``, ``__dataframe__``, etc.
+to facilitate other libraries to consume a Modin DataFrame. If you feel that a certain library
+can operate efficiently with a specific format of data, it is possible to convert a Modin DataFrame
+to the format preferred.

+---------

+
+to_numpy
+--------
+
+.. code-block:: python
+
+    from modin.pandas.io import to_numpy
+
+    numpy_arr = to_numpy(modin_df)
