As soon as you create an account you can make your artist profile - yes, even before you make a release!
Just login to your artist account and scroll down on the page. After entering your artist name you can choose the end of your unique profile URL, and complete your bio in the About section. Put as much relevant information as you can in the About section, you can even embed your YouTube videos by pasting the URL/s in with the text.
Upload your best high quality artist image, and include links to all your social media accounts so it's easy to find and follow you.
