+= Task Events
+
+This is a task application that emits batch job events to the following channels:
+
+	* job-execution-events
+	* step-execution-events
+	* chunk-events
+	* item-read-events
+	* item-process-events
+	* item-write-events
+	* skip-events
+
+Note: More information on this topic is available https://docs.spring.io/spring-cloud-task/current-SNAPSHOT/reference/htmlsingle/#stream-integration-batch-events[here].
+
+== Requirements:
