-The postprocessing of the output data into a format for postprocessing is model specific but similar across models. A new model
-or the same model with different parameters (such as years of analysis) can be adapted from current scripts using the directions 
-in the `README <https://code.ornl.gov/LIVVkit/lex/blob/master/postproc/README_scripts.md>`.
+All the *model* data used for these analyses, and provided as an example, required some
+postprocessing to generate the required input data for analysis with LIVVkit. A set of task-parallel
+postprocessing scripts are provided in the ``postproc`` directory. While these scripts are
+currently model specific, a new model can be adapted from current scripts using the directions in
+the `postprocessing README <https://code.ornl.gov/LIVVkit/lex/blob/master/postproc/README.md>`__.
+Note: A more generalized method of postprocessing model data is currently under development.
