This tutorial-by-example has not yet been created. For now, to determine the proper use of PyRK, check out the tests as well as the Examples.
In a very simple sense, a pyrk simulation is typically run with:
python /path/to/pyrk/driver.py --infile=infile --plotdir=out
In the example above, path/to/pyrk is, of course, the path to the pyrk directory, containing driver.py.
