If you need to add a button over your slide, you can use either text or button layer. To specify the layer, you need to use ms-layer class name and set the type by data-type="button" or data-type="text"same as other layer types. The example below shows how to add a button over a slide.
	<div id="masterslider" class="master-slider">
		<div class="ms-slide">
			<!-- .... -->
            <a href="#" data-type="button" class="ms-layer">
                Button label
            </a>
            <!-- or -->
            
            <div class="ms-layer" data-type="text">
            	<a href="#">
                	Button label
            	</a>
            </div>
			<!-- .... -->
		</div>
