<h1>it Works</h1>
<p>
If you see this, it means the tiny li'l website in your ESP8266 does actually work.
<ul>
<li>If you haven't connected this device to your WLAN network now, you can <a href="/wifi">do so.</a></li>
<li>You can also control the <a href="led.tpl">LED</a>.</li>
<li>And because I can, here's a link to my <a href="http://spritesmods.com/">website</a></ul>

If there's a LED connected to GPIO2, it's now %ledstate%. You can change that using the buttons below.
