for step by step implementation refer this link, for github code

for only show level 0 categories your template look like

<?php
$categories = $this->getStoreCategories(true,false,true);
$categoryHelper = $this->getCategoryHelper();
?>
<ul>
<?php
foreach($categories as $category):
     if (!$category->getIsActive()) {
        continue;
     }
?>
<li><a href="<?php echo $categoryHelper->getCategoryUrl($category) ?>"><?php echo $category->getName() ?></a></li>
<?php   
endforeach;
?>
</ul>
