The Social Links extension pack

I purchased the Social Links extension pack for $5, because it seemed like an easy way to add SoundCloud and Spotify icons to my music website. Now that I have the pack, however, I don’t know what to do with it. Logically, it seems like I need to insert some of the code from the-social-links-pack.php into the already-installed plugin, but as a non-developer I don’t know which code or where. Has anyone ever come across a set of rudimentary, step-by-step instructions for how to handle what is probably a simple set of tasks?
