<h1>Blue Twilight Setup</h1>
<p>We need to download a few things - namely <a href="http://getcomposer.org" target="_blank">Composer</a> and related packages - before we can kick off the Blue Twilight installer.</p>
<p>We can do this for you - simply click the button below.</p>
<p style="font-weight: bold; color: #ff0000;">This can take a few minutes so please be patient!</p>

<h2>Got Composer?</h2>
<p>If you already have Composer installed, however, you may want to use that instead. Just run the below commands on your server, changing the path to Composer as appropriate:</p>
<p><em>Please note: &quot;composer.phar&quot; may actually be &quot;composer&quot; on your system.</em></p>
<pre>cd <?php echo $this->baseDirectory; ?><br/>/path/to/composer.phar install</pre>
