Hi @photory,
These are the instructions from the readme file:
== Social Links ==
To add social links to the sidebar on desktop and menu area on mobile/tablet, follow the instructions below.
- Go to Administration Panel > Appearance > Menus.
- Click on “Create a new menu”. Give your menu a name, like “Social menu”, and click the “Create Menu” button to the right.
- Add a “Custom Link” for each social network link you want to display. The theme will select the appropriate icon for the link automatically, based on the URL.
- Under the “Menu Settings” title, check the checkbox labelled “Social links”. This will instruct the theme to display your links in the social menu area. Click the “Save Menu” button.
- Your social menu should now be visible on the site.
