Be sure that your ranking wasnt created before. Despite you have total freedom to duplicate rankings; our Rankers always value unique content.
If your ranking contains images and/or videos, you can upload them from archive or url. We recommend to prepare all that stuff before you start. It will be faster and agile.
Think about the title, description and tags you plan to put in order to be your ranking findable for search engines and other Rankers.
