When writing a project brief, always keep in mind: the more details the better.
Don’t forget to add all links related to your website/project.
Also remember to add any attachments if needed. You will have the ability to add attachments once you post your project and are in your workroom.
Last but not least, set a realistic deadline and a realistic budget.
