We have included a theme specific shortcode for Forest, that outputs a number of social media icons.
You can use the following shortcode to display social links anywhere between posts, pages or text widget:
[social url="facebook,twitter,dribbble,google-plus,pinterest,vimeo,forrst,linkedin,instagram,deviantart,flickr,youtube,myspace,soundcloud,behance"]
As you can see above, you can enter the social media name and it will automatically insert the icons.
The above shortcode will display all social media icons. For your case, keep the social media names that you need and get rid of the ones you don’t.
You can customize all the social media links under Theme Options > Social Settings.
