+### Showing My Work
+
+Since the approximations in this library are primarily based on
+polynomial approximations, I've tried to provide the details
+for how those polynomials were derived, by providing a zipped
+folder containing the Mathematica notebooks that were used to
+derive the polynomials. Since not everyone has access to
+Mathematica, the folder also contains a PDF version of the
+notebook. At the moment, I'm planning to upload an updated
+copy of the zipped folder with each release of the library,
+but if I can think of a better method of distribution, that
+doesn't involve adding the notebook files to the repository
+directly, I'll do that instead.

 ### Measuring Accuracy
 
 This library uses three approaches for measuring accuracy:
