-This lesson will take you through a tutorial that will teach you the basic modules and functions that you need to get up and running with Node.js. The project that comes at the end of this section will ask you to use Node to create a basic website that will include an `Index`, `About` and `Contact Me` page. So while learning the topics in this lesson, be on the lookout for things that might help you complete the project.
