-=== type ===
+<param type> can be either 'KIM_PARAM' for a regular parameter of 'KIM_CUTOFF' for the cutoff parameter of a model. If you don't know if the model publishes the cutoff as an independent parameter just use 'KIM_PARAM' for all parameters.
+<param_name> has to be exactly the same string as the model uses in the published parameter list.
+Depending on the dimensionality of the parameter, it requires N lines of values, which consist of the initial value, the minimum and maximum allowed values.
+Here is an example for the OpenKIM model 'ex_model_Ar_P_LJ' which publishes three parameters, which all have the dimension 1:
+<code>
+#F 5 1
+#T ex_model_Ar_P_LJ
+#C Ar
+#E
+KIM_PARAM cutoff
+.150000        8.150000        8.150000
+KIM_PARAM epsilon
+.010400        0.010400        0.010400
+KIM_PARAM sigma
+.400000        3.400000        3.400000

+===== Additional features =====
+====  Global parameters  ====
+//potfit// supports global parameters also for OpenKIM potentials. A detailed explanation can be found on the [[format0|analytic potentials]] page.
