Hello @mercury913,
Thanks for asking. 
You need to create the relevant sections and after each section in which you will add the content, you need to create a new section to display scroll down arrow button. Please add following code in text element to display scroll down arrow button:
<a href="#x-section-2" class="x-slider-scroll-bottom above bottom center">[icon type="angle-down"]</a>
You must link it to the next section which in your case it would be #x-section-2.
To help you get started I have recorded a screencast that you can take a look. https://cl.ly/2I2L0b1W0S1Z
You can get the list of icon codes here. http://demo.theme.co/integrity-1/shortcodes/icons/
Hope that helps you to get started.
Thanks.
