 The project starts a server providing an endpoint to handle REDCap notifications. Then, Data Entry Trigger of a 
 REDCap can be configured to send notification to http://localhost:8095/tofhir-redcap/notification endpoint (if you use default configurations).
 
+Whenever this endpoint receives a notification about a record, it exports its data via REDCap API and publishes record data
+to a Kafka topic which is the concatenation of project id and instrument name such as '27-patient'.
+
 # Configuration
 Please see [application.conf](src/main/resources/application.conf) for the configurations. It allows you to configure Web server settings, Kafka
 and REDCap projects.
