Create a folder sections in your theme's directory. Add custom sections by adding a .PHP file for each section.
Define editable areas in custom section like this:
<section class="well-4">
<div class="container">
// editable text (inline-level elements only)
<?php echo $s->text('h3', 'head', 'Latest News')?>
// editable image
<?php echo $s->img('myimage', 'images/default.jpg', 99, 99, 'img-circle') ?>
// editable rich text (allows block-level elements)
<?php echo $s->richtext('div', 'head', '<p>Lorem ipsum<br>dolor sit amet</p>')?>
</div>
</section>
