Cameron Hummels:

have one single location explaining how to get the sample datasets (and link to it in all of the other mentions of it).  also explain how setting up a line in their config file will allow them to execute it without being in the local sample data directory.  

potentially this line in the config file annotation would go in the config file explanation.
