 The [Speedfony Bundle](https://github.com/PHPFastCGI/SpeedfonyBundle) integrates this daemon with the symfony2 framework.
 
+## Usage
+
+Below is an example of a simple 'Hello, World!' FastCGI application in PHP.
+
+```php
+<?php // application.php
+
+// Include the composer autoloader
+require_once dirname(__FILE__) . '/../vendor/autoload.php';
+
+use PHPFastCGI\FastCGIDaemon\Command\DaemonRunCommand;
+use PHPFastCGI\FastCGIDaemon\DaemonFactory;
+use Psr\Http\Message\ServerRequestInterface;
+use Symfony\Component\Console\Application;
+use Zend\Diactoros\Response\HtmlResponse;
+
+// Create the dependencies for the DaemonRunCommand
+
+// Dependency 1: The daemon factory
+$daemonFactory = new DaemonFactory();
+
+// Dependency 2: A simple kernel. This is the core of your application
+$kernel = function (ServerRequestInterface $request) {
+    return new HtmlResponse('<h1>Hello, World!</h1>');
+};
+
+// Create an instance of DaemonRunCommand using the daemon factory and the kernel
+$command = new DaemonRunCommand('run', 'Run a FastCGI daemon', $daemonFactory, $kernel);
+
+// Create a symfony console application and add the command
+$consoleApplication = new Application();
+$consoleApplication->add($command);
+
+// Run the symfony console application
+$consoleApplication->run();
+```
+
+If you wish to configure your FastCGI application to work with the apache web server, you can use the apache FastCGI module to process manage your application.
+
+This can be done by creating an FCGI script that launches your application and inserting a FastCgiServer directive into your virtual host configuration.
+
+```sh
+#!/bin/bash
+php /path/to/application.php run
+```
+
+```
+FastCgiServer /path/to/web/root/index.fcgi
+```
+
+If you are using a web server such as nginx, you will need to use a process manager to monitor and run your application.

 ## Current Status
 
 This daemon is currently in early development stages and not considered stable. A stable release is expected by September 2015.
