Each contest is unique and often there are contest specific rules that you should be aware of. To find the judging rubric and breakdown of points for the specific contest you are participating in, go to the "Judging criteria" section in the contest rules.
In addition to specific judging criteria, please note that your final project must also consist of the following materials:
Project title, description and cover image
Bill of materials
Full instructions (story) and images
Source code via Github or Bitbucket
Electronics schematics
CAD files if any
Adding a video is a great way to enhance your project, but it is not required unless specified in the contest rules.
