 # cics-eventprocessing-java
 
-Example code of how to use CICS event processing in the Java programming language
+This Java web application demonstrates how to emit and consume CICS events in Java using the JCICS API.
+
+## Requirements
+
+* CICS TS V5.3 or later
+* A configured Liberty JVM server
+* Java SE 1.8 or later on the z/OS system
+* Java SE 1.8 or later on the workstation
+* Either Gradle or Apache Maven on the workstation (optional if using Wrappers)
