 Once you are able to build the neic-locator jar, simply include the jar
 file in your application, or call using the LocMain class.
 
+A set of model files used by the locator is stored in the models/ directory.
+The locator also requires traveltime model files. These files are copied into
+build/models/ as part of the gradle build.
+
+An example legacy input file (LocOutput1000010563_23.txt) is provided in the
+examples directory.
+
+To run this example, run the command  `java -jar neic-locator-0.1.0.jar --modelPath=./models/ --eventFile=./`
+
+This example assumes that a sub-directory containing the locator and traveltime 
+model files, as well as the example input file are located in the same directory
+as the locator jar file.
