 ===========
 
+A collection of diagnostic and interpolation routines for use with output from 
+the Weather Research and Forecasting (WRF-ARW) Model.
 
-wrf-python is a package to help users working with the Weather 
-Research and Forecasting Model (WRF-ARW) output.  wrf-python includes over

+This package provides over 30 diagnostic calculations,

+via cartopy, basemap, or PyNGL. The functionality is similar to what is 
+provided by the NCL WRF package.
