Customizing the social menue

Hello @spiresawake,
First of all thanks for using Biography theme.

For social icons, currently the free version of the theme only supports social networks such as facebook, twitter and linkedin.
However, if you want to add more social networks then the only way would be customizing your theme by making a child theme. You can get hints to make the child theme from here: https://codex.wordpress.org/Child_Themes#How_to_Create_a_Child_Theme

Thanks!
