This field tells the contractor specifically what you're looking for in the Deliverable. If the Deliverable is artwork, for example, the description can be an art brief ("A brown horse jumps over a fire, its eyes wide with panic"), a technical description ("A full-color illustration, no smaller than 10x8" at 300dpi"), or both. The description appears on the Deliverable's review page, and may appear in its contract if the template is set up to include it.
