Can you tell me what to do before registering an item as an author?

Hello, I am trying to upload a css item to envato market.

I think it is possible to upload the item itself just by signing up, but I am asking for feedback on the forum because I think I need to register and upload the following information first.

I would be grateful if you let me know if there is any missing content or order in order to register the item

1. Membership 2. Personal profile setting and item sales support setting 3. Set the way to receive sales revenue (paypal, etc.) 4. Upload items

Do I have to apply by entering the url below?

That’s the right list of things - although, of course, there is more to uploading than just sending the file - you need to do the documentation and other requirements
