+DESCRIPTION = 'A python toolbox for analyzing and plotting free recall data'
+LONG_DESCRIPTION = """\
+Quail is a Python package that facilitates analyses of behavioral data from memory experiments. (The current focus is on free recall experiments.) Key features include:
+
+- Serial position curves (probability of recalling items presented at each presentation position)
+Probability of Nth recall curves (probability of recalling items at each presentation position as the Nth recall in the recall sequence)
+- Lag-Conditional Response Probability curves (probability of transitioning between items in the recall sequence, as a function of their relative presentation positions)
+- Clustering metrics (e.g. single-number summaries of how often participants transition from recalling a word to another related word, where "related" can be user-defined.)
+- Many nice plotting functions
+- Convenience functions for loading in data
+- Automatically parse speech data (audio files) using wrappers for the Google Cloud Speech to Text API
+
+The intended user of this toolbox is a memory researcher who seeks an easy way to analyze and visualize data from free recall psychology experiments.
