In order to upload the related documents, you need to login in your user profile and then choose the "Paper submission" link. The 5-step submission process including the title, authors' names, abstract part, the full paper part, would be compeleted as the requested way. Noted that the abstract files must be written and pasted just in English. But there is not a fixed rule for the full papers. You may prepare your paper as Abstract or full text based on appropriate Persian or English template.
