+<h1>{{title}}</h1>
+
+<p>
+The Lospec Pixel editor is a free pixel art program that you can use right here 
+in your web browser. Our goal was to create an easy to use, intuitive and 
+unobtrusive pixel art application that you can use anywhere. Whether you're 
+creating assets for a game or just want to make 8 bit art, this tool is an easy 
+way to pixel fast.
+</p>
+
+<img class="pixel-editor-screenshot" src="/pixel-editor/pixel-editor-screenshot.png" alt="Lospec Pixel Editor Screenshot" />
+
+<p>
+This application does not have all the features of more advanced desktop editor, 
+but we will add more over time. Desperate for a feature? Talk about it with us 
+in the <a target="_blank" href="http://reddit.com/r/lospec">Lospec subreddit</a>. 
+It currently features a pencil, fill, pan, eyedropper 
+and zoom tool. You can also easily adjust any colors in your palette. You can 
+use any palette in our <a href="/palette-list">Palette List</a> by clicking the pencil next to the palette 
+title. 
+</p>
+
+<p>
+This app currently only works on desktops, and requires a modern browser such as 
+the latest versions of <a target="_blank" href="https://www.mozilla.org/en-US/firefox/new/">Firefox or Chrome</a>.
