-A collection of tools for timeseries
+This module contains all the integer frequency constants. Below is a detailed
+description of the constants, as well as a listing of the corresponding string
+aliases.
 
+All functions in the timeseries module that accept a frequency parameter can
+accept either the integer constant, or a valid string alias.

+|----------------------------------------------------------------------------|
+|CONSTANT         | String aliases (case insensitive) and comments           |
+|----------------------------------------------------------------------------|
+| Note: For annual frequencies, "Year" is determined by where the last month |
+| of the year falls.                                                         |
