# Installation

 Atom utilizes [Composer](https://getcomposer.org/) to manage its dependencies. So, before using Atom, make sure you have Composer installed on your machine.

### Installing using Composer

```
composer create-project frameworkatom/atom project-name
```

Replace "project-name" with your project name.<br>

### Local Development Server

&#x20;If you have PHP installed locally and you would like to use PHP's built-in development server to serve your application, you may use:

```
php atom serve

#or

php atom s
```

This command will start a development server at `http://127.0.0.1:2019`<br>
