Social Media Icons

Hello. Sorry I have posted quite a few questions tonight. I love the theme and very excited to use it. Thank you!

My question here is what would be the best way to include small social media icons in the footer area. Looking to include Facebook, Twitter and Instagram. I wasn’t sure if this was something included with the theme but I did not see it in the widgets panel, or I need to get a plugin or something else.

thank you!
