<h1>
	Welcome to ${snoot}'s homepage
</h1>

<p>
	if you are <strong>${snoot}</strong>, you can now ssh or ftp into your account!
</p>

<p>
	the page you are reading right now is the file located at
	<code>./application/website/index.html</code>
</p>

<p>
	the start script in your <code>package.json</code> will be run automatically.
	you can replace it with anything, and as long as it creates and listens on a
	unix domain socket at <code>./application/sock</code>, it'll be served. the
	initial setup already does this, and serves files in
	<code>./application/website</code> and apps in
	<code>./application/boops</code> using <a
	href="https://github.com/snootclub/boop">boops</a>.
</p>

<p>
	i promise that's cool and fun
</p>
