+## Setup for ismdust fits with ISIS (Interactive Spectral Interpretation System) models
+
+Add a line to your .isisrc file
+
+    add_to_isis_load_path("/path/to/ismdust/ismdust_isis");
+
+Set an environment variable (same way you would for the XSPEC model)

+
+    isis> fit_fun("ismdust(1, powerlaw(1))");
