Setting up neo4j with javascript

I need a step-by-step guide to setting up neo4j to work with a website using javascript/jquery (maybe node.js?).

Do I need this: https://github.com/neo-technology/neo4js

or this: https://github.com/thingdom/node-neo4j

I want to use it as a backend server to a website, using the cypher language to manipulate the graph database itself. I dont need help with general graph db layout or the cypher language, just how to make it work(!) from a website environment.

I really need some help with this
