Chapter 5, duplicated paragraph
The following paragraph is duplicated in chapter 5 > Create RESTful services > Conventions:
"Another frequently occurring convention that is important to the deployment of Node.js services is a standard approach to starting the Node.js process. The standard approach is to have a start field in the scripts object of the package.json file so that the process can be started with npm start. The npm start command will execute the contents of the start field as a shell command."
By the way, I have seen some messages in this forum informing of typos. Do you prefer another ticket system to do so, or maybe a general forum thread to collect all the typos?
