Add a Gadget/Widget is a fairly simple process with all of our themes.
1. Log into your Blogger dashboard and go to Layout > Sidebar > Social Media > Link List. Click on Edit.
2. On the bottom click the "Add a new item" button to add a list. Add the "Name" and "Link".
3. In "Site name" add the name Social Media and in "Site URL" add the URL the your Social Media. Click on Save.
By adding the name of the social media, its icon will appear automatically.
