 A simple SFF file viewer has been added to [dev/sff](dev/sff) and serves as a demonstration of how the `SFF` module can be used to generate spectrogram images from SFF files.
 
 ### Read SFF Files with Python
-A Python module to read SFF files has been created (in [dev/sff](dev/sff)) which allows Spectrograms created by this library and stored in SFF format to be loaded as 2D numpy arrays in Python.

-This example demonstrates how the SFF file created in the previous C# example can be loaded into Python and displayed with matplotlib. This example has a few lines related to styling omitted for brevity, but the full Python demo can be found in [dev/sff](dev/sff).
