Import the velocity engine,
invoke the file(style sheet, etc) which you are going to display,
and rest of the stuffs are same as invoking classes from another

You can use the Velocity in Liferay portal.

Here is an real example for navigation.

Codes: navigation.vm

<div id="navigation">
<ul>
#foreach ($nav_item in $nav_items)
#if ($nav_item.isSelected())
#set ($nav_item_class = "selected parent-nav-item")
#else
#set ($nav_item_class = "parent-nav-item")
#end

<li class="$nav_item_class">
<a href="$nav_item.getURL()" $nav_item.getTarget()><span>$nav_item.getName()</span></a>

#if ($nav_item.hasChildren())
<ul class="child-menu">
#foreach ($nav_child in $nav_item.getChildren())
<li>
<a href="$nav_child.getURL()" $nav_child.getTarget()>$nav_child.getName()</a>
</li>
#end
</ul>
#end
</li>
#end
</ul>
</div>
