# Overview

Let's have a quick look at the project scaffold. We'll have a look at even more details in the Architecture section.

`/public` - output of packaged app 

`/src` - this is what you will be using during development. NPM calls rollup, and together they move and transform the files from /src to /public.

`package.json` - manifest file for your project(kind of). Lists details of your project(names), main entry point in the app(main.js), and external dependencies(think maven/ivy for Java world, composer for php, PyPM for Python). See [NPM(and package.json)](https://app.gitbook.com/@dashboard-hero/s/dashboard-hero/basics/npm-and-package.json) for more details.

Rollup - a tool that compiles small pieces of code into something larger. In a nutshell, it scans src/(that might contain `import` and `require` statements, for instance) and produces /public(parts of it, anyway) that the browser can understand and interpret.

`rollup.config.js` - configuration for Rollup. `input` - This is a required setup and it represents the file we want rollup to process. It should be the main entry point of the application where we import everything else required by it. `output` - marks the folder where the results gets copied. Since we're just talking about the scaffold, we'll leave it at this, for now. See [Rollup(and rollup.config.js)](https://app.gitbook.com/@dashboard-hero/s/dashboard-hero/~/edit/drafts/-LiO0jIpUMx0pUpSTkUc/basics/rollup) for more details.
