i dont understand the profile avatar please guide me im noob af tia!

So the first part would of course, be to decide on what you want as an avatar. If you have a link, with a picture in mind I would be more than happy to help you set it up

This screen shot should give you most of the info you're looking for. (Obviously don't use my avatar)

Go to an uploading website, imgbb or imgur, upload your image, and copy/paste the image URL as shown in the screenshot. Make sure your avatar URL ends in a .gif, .png, or .jpg or else it won't work.
