+= TaskProcessor
+
+Is a stream processor that will accept messages with a string payload and create a
+`TaskLaunchRequest` that it will send to the next app in the stream.  The payload of the
+message that is sent will be added to the properties of the `TaskLaunchRequest` under
+the `payload` key.
+
+By default the processor will add the timestamp-task sample coordinates if no task is
+specified.
+
+NOTE: if using defaults make sure to install the timestamp-task into your local maven repo
+by executing the following build in the timestamp-task module:
+
+[source,shell,indent=2]
+----
+$ ./mvnw clean install -DskipInstall=false
+----
+

+* *group* establishes the group for the task maven coordinates.   Default is `io.spring`.
