-The project is composed by 2 parts:
+== Motivation
 
+Many user and customers want to integrate Kakfa and other streaming solutions with Neo4j.
+Either to ingest data into the graph from other sources.
+Or to send update events (change data capture - CDC) to the event log for later consumption.
+
+This extension was developed to satisfy all these use-cases and more to come.
+
+The project is composed of several parts:
+
+* Neo4j Streams Procedure: a procedure to send a payload to a topic
 * Neo4j Streams Producer: a transaction event handler events that sends data to a Kafka topic
 * Neo4j Streams Consumer: a Neo4j application that ingest data from Kafka topics into Neo4j via templated Cypher Statements
 
+In the next releases we will add Kafka-Connect connectors as well.
+
