How to install Neo4j?

• NOTE: Neo4j Configuration Details - Open the file neo4j-server.properties, which is in the folder %Neo4j%\conf, in texteditor. Find the line org.neo4j.server.database.location=data/graph.db and point to the database you want to access. In my case, this is the Phylet database, so this line reads org.neo4j.server.database.location=data/phylet.db. If you don’t have a Neo4j database built yet, leave this line as-is.
