This book can be read without any additional resources; however, we recommend access to some physical lab resources to install Neo4j Community Edition on. You can download that software from http://neo4j.com/download/ at your convenience.

A reasonable and recommended lab setup can be one on a machine with a dual or quad-core processor with 8 GB of RAM. A system with a lesser configuration would probably also work, but the recommended one will make it more comfortable for you.

Also note that you need OpenJDK 7 (http://openjdk.java.net/) or Oracle Java 7 (http://www.oracle.com/technetwork/java/javase/downloads/index.html) installed on your machine.
