    <h2>Post Tiles:</h2>
    <h3>How to use Post Tiles:</h3>
        <ul>
            <li>1.) To add posts tiles to a page or post copy and paste the following shortcode. Example: <strong>[post-tiles]</strong></li>
            <li>2.) By default 8 posts are displayed. To change the amount of posts to display, use the <strong>posts=' '</strong> attribute in the shortcode. Example: <strong>[post-tiles posts='10']</strong></li>
            <li>3.) By default all post categories are called for the tiles. To specify the categories use the <strong>categories=' '</strong> attribute separating them by commas. Example: <strong>[post-tiles categories='1,2,4']</strong></li>
            <li><div id='tc-note'><em><strong>NOTE:</strong> The category id numbers are listed below, next to the category names. You can use both the categories and posts attributes Example: <strong>[post-tiles categories='1,2,4' posts='8']</strong></em></div></li>
            </ul>
    <div id='color-container'>
    <div id='color-picker-example'>

    </div>
    <form method='POST' action='options.php'><div id='category-list'><h3>Pick Your Cutom Tile Colors:</h3><em>1.) Click inside each of the category inputs. <br/>2.) Next use the color picker on the left to select the color for that categories tiles.<br/>3.) Save Your Changes</em><ul>";
