-This brings additional support for the Neo4j 4.0 Test Harness to the Driver starter:
+This brings additional support for the Neo4j Test Harness to the Driver starter:
 
 * It brings in the correct dependencies
 * It provides auto configuration for the Test Harness:
 ** If there's a `Neo4j` bean instance, it configures a corresponding `Driver` bean that uses it
 ** If the test harness is available and there's no `Neo4j` bean, it creates one and opens a `Driver` instance to it.
+
+The module uses Neo4j 3.5.x Test Harness by default, so that the overall build of this project can stay on JDK 8. 
+You can however replace the 3.5.x dependencies with the corresponding 4.0 one without further configuration to benefit from Neo4j 4.0.
