+pytokio is a Python library that provides the APIs necessary to develop analysis
+routines that combine data from different I/O monitoring tools that may be
+available in your data center.  However several simple utilities are included to
+demonstrate how pytokio can be used in the `bin/` directory.
+
+Additionally, the pytokio git repository contains several other examples and
+tests to demonstrate the ways in which pytokio can be used.
 
-- `bin/` directory contains useful tools implemented on top of pytokio
 - `examples/` contains standalone Jupyter notebooks and scripts that illustrate
   different aspects of the pytokio API that do useful things.  They are designed
   to run on NERSC systems via https://jupyter.nersc.gov/.
 - `tests/` contains unit and integration tests for the pytokio library and
    the scripts bundled in `/bin`
-- `tokio/` is the importable Python package itself
