			If you use just procedural geometries and don't load any textures, webpages should work
			straight from the file system, just double-click on HTML file in a file manager and it
			should appear working in the browser (you'll see <em>file:///yourFile.html</em> in the address bar).
		</p>

		<h2>Content loaded from external files</h2>
		<div>
			<p>
				If you load models or textures from external files, due to browsers' [link:http://en.wikipedia.org/wiki/Same_origin_policy same origin policy]
			 	security restrictions, loading from a file system will fail with a security exception.
		 	</p>

			<p>There are two ways to solve this:</p>

			<ol>
				<li>
					Change security for local files in a browser. This allows you to access your page as: <code>file:///yourFile.html</code>
				</li>
				<li>
					Run files from a local web server. This allows you to access your page as: <code>http://localhost/yourFile.html</code>
				</li>
			</ol>

			<p>
				If you use option 1, be aware that you may open yourself to some vulnerabilities if using
				the same browser for a regular web surfing. You may want to create a separate browser
				profile / shortcut used just for local development to be safe. Let's go over each option in turn.
			</p>
		</div>


		<h2>Run a local server</h2>
		<div>
			<p>
				Many programming languages have simple HTTP servers built in. They are not as full featured as
				production servers such as [link:https://www.apache.org/ Apache] or [link:https://nginx.org NGINX], however they should be sufficient for testing your
				three.js application.
			</p>

			<h3>Node.js server</h3>
			<div>
				<p>Node.js has a simple HTTP server package. To install:</p>
				<code>npm install http-server -g</code>

				<p>To run (from your local directory):</p>
				<code>http-server . -p 8000</code>
			</div>

			<h3>Python server</h3>
			<div>
				<p>
					If you have [link:http://python.org/ Python] installed, it should be enough to run this
					from a command line (from your working directory):
				</p>
				<code>
//Python 2.x
python -m SimpleHTTPServer

//Python 3.x
python -m http.server
				</code>

				<p>This will serve files from the current directory at localhost under port 8000, i.e in the address bar type:</p>

				<code>http://localhost:8000/</code>
			</div>

			<h3>Ruby server</h3>
			<div>
				<p>If you have Ruby installed, you can get the same result running this instead:</p>
				<code>
ruby -r webrick -e "s = WEBrick::HTTPServer.new(:Port => 8000, :DocumentRoot => Dir.pwd); trap('INT') { s.shutdown }; s.start"
				</code>
			</div>

			<h3>PHP server</h3>
			<div>
				<p>PHP also has a built-in web server, starting with php 5.4.0:</p>
				<code>php -S localhost:8000</code>
			</div>

			<h3>Lighttpd</h3>
			<div>
				<p>
					Lighttpd is a very lightweight general purpose webserver. We'll cover installing it on OSX with
					HomeBrew here. Unlike the other servers discussed here, lighttpd is a full fledged production
					ready server.
				</p>

				<ol>
					<li>
						Install it via homebrew
						<code>brew install lighttpd</code>
					</li>
					<li>
						Create a configuration file called lighttpd.conf in the directory where you want to run
						your webserver. There is a sample [link:http://redmine.lighttpd.net/projects/lighttpd/wiki/TutorialConfiguration here].
					 </li>
					<li>
						In the conf file, change the server.document-root to the directory you want to serve files from.
					</li>
					<li>
						Start it with
						<code>lighttpd -f lighttpd.conf</code>
					</li>
					<li>
						Navigate to http://localhost:3000/ and it will serve static files from the directory you
						chose.
					</li>
				</ol>
			</div>

				on Stack Overflow.
