It’s so easy, it’s ridiculous:
Go to your profile page settings. https://app.hackernoon.com/profile
On the tab “Details” you’ll see all your profile information, including handle, display name, bios, social media links, and of course, your avatar!
Click the “Create Avatar” button - you can’t miss it! It has a yellow banner, for godsakes!
Have fun creating your avatar!
Hit “Save Avatar” and it’ll automatically replace your old placeholder image.
