Personally I didn't like your main text introduction: "Don't waste hours, days or weeks researching server-side JavaScript, cloud providers and NoSQL, and then compiling, configuring and deploying the systems from scratch. Get a preconfigured virtual server with a running sample application powered by Express.JS."

Primarily the first sentence was a huge turn-off for me. Researching your technology and understanding it is never a waste of time. And Server-Side JavaScript is not some magic bullet where you need to know nothing but can write amazing applications. It is a tricky environment with some great power and massive 'gotchas'.

Personally I think you should either remove reference to research or fully embrace the word. A sales point could be more along the lines of: "Popular server-side JavaScript frameworks already connected and configured to allow you to jump directly into a working example. Great for bootstrapping your research project or spinning up servers for your already written application!" But, I have no silver-tongue so take my wording advice with caution. ;)
