 ## Prerequisites
+You can install the tools you'll need for this tutorial with one click by using the [Node.js tutorial setup script](http://boxstarter.org/package/url?https://raw.githubusercontent.com/Microsoft/Dev-Advocacy-Samples/master/nodejs_tutorial_setup.ps1) based on the [Windows Dev Box Setup Scripts](https://github.com/Microsoft/windows-dev-box-setup-scripts) project. 
+
+Alternatively, follow the steps below to install prerequisites.
+
 1. Install Visual Studio Code for Windows [here](https://code.visualstudio.com/Download) 
 2. Make sure WSL is set up on your machine. You can follow the installation instructions [here](https://docs.microsoft.com/en-us/windows/wsl/install-win10).
 3. You need to have installed Node and NPM. See https://gist.github.com/micahgodbolt/8b9a338c8bab7bc147975646ea20826c
 
 ## Tutorial
-1. Clone this repository

+1. Create a user called 'ubuntu' that you will use throughout this tutorial. In you Ubuntu 18.04 terminal type the following:
 ``` shell
-git clone https://github.com/Microsoft/Dev-Advocacy-Samples.git
+sudo adduser ubuntu
+```
+Add 'ubuntu' to the sudo user group
+``` shell
+sudo adduser ubuntu sudo
+su - ubuntu
 ```
 
-2. Go to `/nodejs-shoppingcart`
+Note that when you create the user you will be promted for a password. Go ahead and create one. You'll also be propted for a few other details. You can skip filling those in by pressing "Enter".
 
-3. Install dependencies
+2. Restart your Ubuntu 18.04 app and install node:
+``` shell
+nvm install node
+```
+Verify node is installed:
+``` shell
+node --version
+v7.4.0
+```

+5. Open this folder in VS Code from your bash terminal
 ``` shell

 ## Debugging
 To debug the Node app running within WSL, we have included a `launch.json` that contains a debug configuration that's launching the Node process for you. This means that you have to stop/kill the existing Node process that you may have started from the integrated terminal. The debug configuration works by running `npm run debug`, which is a predefine npm script in the `package.json` which starts the node process with the debug `--inspect` flag. Notice that the `useWSL` property is set too, and this tells VS Code to use WSL, so the launched Node process runs within WSL and not Windows.

 ## Azure & Next Steps
 We also included a workspace recommendation that enables you to install the [Azure App Service extension for VS Code](vscode:extension/ms-azuretools.vscode-azureappservice), that allows easy deployment to Azure (from within VS Code).
