 This is a complex mod example demonstrating an area chart rendered with `d3` and bundled with `Webpack`.
 
 All source code for the mod example can be found in the `src` folder. Other necessary files reside in the `static` folder. Read below for further explanation.
 
 ## Prerequisites

 These instructions assume that you have [Node.js](https://nodejs.org/en/) (which includes npm) installed.
 
 ## How to get started (with development server)
+
 - Open a terminal at the location of this example.
 - Run `npm install`. This will install necessary tools. Run this command only the first time you are building the mod and skip this step for any subsequent builds.
 - Run `npm start`. This will bundle the JavaScript and place it in the `dist` folder. This task will watch for changes in the code and will continue running until it is stopped. Whenever you save a file, the changes will be reflected in the visualization mod.

 ## Working without a development server
+
 - Open a terminal at the location of this example.
 - Run `npm install`. This will install necessary tools. Run this command only the first time you are building the mod and skip this step for any subsequent builds.
 - Run `npm run build`. This will bundle the JavaScript and place it in the `dist` folder. It also copies the contents of `static` into `dist`. This task will not watch for changes in the code.
