+# motorAcs
+EPICS motor drivers for the following [Advanced Control Systems Corporation](http://www.acsmotion.com) controllers: MCB-4B
+
+motorAcs is a submodule of [motor](https://github.com/epics-modules/motor).  When motorAcs is built in the ``motor/modules`` directory, no manual configuration is needed.
+
+motorAcs can also be built outside of motor by copying it's ``EXAMPLE_RELEASE.local`` file to ``RELEASE.local`` and defining the paths to ``MOTOR`` and itself.
+
+motorAcs contains an example IOC that is built if ``CONFIG_SITE.local`` sets ``BUILD_IOCS = YES``.  The example IOC can be built outside of driver module.
