“Hi! I just put bonefinger on my blog because I think it looks really good, but I never do anything with coding. How do I add an icon on the left side there? And add the links to those other social media sites at the bottom?”

Once you install the theme, save and close your editor. Reopen the editor and there will be a long list of custom variables on the left side. The one labeled “Logo” is the icon. To add your social media sites, just put your username(s) in the corresponding boxes.
