-Note that in LAMMPS lingo, a KIM model driver is a pair style
-(e.g. EAM or Tersoff).  A KIM model is a pair style for a particular
-element or alloy and set of parameters, e.g. EAM for Cu with a
-specific EAM potential file.

+In KIM lingo, a potential is a "model" and a model contains both the
+analytic formulas that define the potential as well as the parameters
+needed to run it for one or more materials, including coefficients and
+cutoffs.
 
 The argument {virialmode} determines how the global virial is
 calculated.  If {KIMvirial} is specified, the KIM model performs the
