 # Using nshmp-haz with Matlab
 
-This is out of date.
-
->**NOTE:** *nshmp-haz* was recently upgraded to Java 8, which supercedes and is
-incompatable with the Java 7 JVM that ships with Matlab. Users will need to set the
-`MATLAB_JAVA` environment variable to point to a Java 8 runtime.
-
-All recent versions of Matlab include a Java runtime environment and it is therefore
-relatively straightforward to use the nshmp-haz library.
-
-## Requirements
-
-1. Matlab R2013B or higher (nshmp-haz targets Java 7; prior versions of Matlab use Java 6).
-2. A [build](https://github.com/usgs/nshmp-haz/wiki/building-&-running) of nshmp-haz.
+The best way to use _nshmp-haz_ with matlab is as a web service. The scripts in this directory
+provide examples of how to access web services for ground motion models (GMMs) that are based
+on the code in this repository.
