 If you want to begin customizing your theme, a useful starting point is to identify a template that you would like to modify -- good starting points are the **header.phtml** and **footer.phtml** files that define VuFind's default header and footer. Copy one of the files from your theme's parent theme into your own, edit the HTML, and see how things change when you access your site through a web browser.
-If you want to begin customizing your styles, you can create a brand new CSS file to override some defaults, and register it in your theme's module.config.php -- or you can use the more advanced [[[[development:architecture:less|LESS]] technology to adjust some variables and recompile VuFind's core CSS with some local adjustments.
+As you do this, you will likely notice bits of code wrapped in "slots". Slots are a [[development:plugins:view_helpers|view helper]] that makes it easy to override and customize content. You can learn all the ways to use them on our [[development:plugins:view_helpers|view helpers page]].
+<code php>
+<?php $this->slot('footer-left')->start(); ?>
+    <p>Custom left foot(er)</p>
+<?php $this->slot('footer-left')->end(); ?>
+<?php include $this->parentTemplate('footer.phtml'); ?>
