-## BUILDING from the sources
+## Building from the sources
 
 As the project is a Maven project, building is rather simple by running:
 
 	mvn package
+    
+The project requires the following to build:
+- Maven 
+- JDK 1.7 or later. The jar will target JDK 1.6, but the version of the maven-compiler-plugin that JsqlParser uses requires JDK 1.7+
 
 This will produce the jsqlparser-VERSION.jar file in the target/ directory.
