Newbie issue - Change social media links (Deliver skeleton)

Hi, I installed GRAV 2 days ago using Deliver skeleton.
Now I’m trying to configure the website to a local astronomy event, but some things seems “misterious” to me.

For example, in the top of main page, we have 3 social media icons. Captura de Tela 2020-11-15 às 03.35.48

How to change this icons (I want to use Facebook and Instagram icons) and how to change the social media URL in this icons?

I searched all the files on the site and found no references to change it. After expend more than 4 hours opening files, I don’t found any way to make this changes. :slight_smile:

Does anyone know how to do this?

PS: website address:

Sorry guys, problem solved! I fund where to change it. In user/config/site.yaml
