+Client requirement:
+java 1.8
+
+To build and run all tests:
+> ./gradlew build --offline
+
+To run the unit tests only:
+> ./gradlew test --offline
+
+To run the application, create a fatJar first, then execute it
+> ./gradlew clean build fatJar --offline
+> java -jar build/libs/ddd-workshop-0.0.1-SNAPSHOT-all.jar
+
+To run with a specific stream, for example: data/1.json, run:
+> java -jar build/libs/ddd-workshop-0.0.1-SNAPSHOT-all.jar ../data/1.json
+
+By default the eventstream is retrieved from the server. In case of network problems Wire the FileEventStreamProvider 
+in the Main class instead of the RestEventStreamProvider. 
+
+There are different streams of events. If no stream is specified the system will default to zero. 
+The stream id is taken as the first argument pass to the application.
+Add the stream id (0,1,2) to the program arguments.
