Social media icons don’t appear in header

Hi there, I'm trying to add social media icons on my website (header) but I just can't figure it out. 'Social options' doesn't appear in 'Theme Options' either. Dot I have to install the pro version to get this option? I don't need to add any customized social icons, the icons featured in the Izabel free demo are perfectly fine. I hope anyone can help me out! Thanks. Rosanne
