Social links is the section of your public profile where you can direct people to your personal website or Facebook, Twitter, Soundcloud, and YouTube accounts. If you don't have one of those, it's ok - you can leave any of those blank.
Here's how to set your social links:
1. Click your profile image in the top right and click View Profile.
2. Now you can see your public profile. To make changes, click the Edit Profile button.
3. After clicking the Edit Profile button, you can make changes to your profile. To edit your social links, click the pencil icon beside the social links.
4. You can add/edit/remove your website or Twitter, Facebook, Soundcloud, or Youtube account. Make changes and click the Save button.
