You should include: jQuery, main slider JavaScript file, main slider CSS file, skin CSS file.
It's recommended to get jquery.royalslider.min.js from build tool and jquery.js from its official site. Always use the latest version. Feel free to combine files in one.
Make sure that paths match locations of files.
