One of the other NCD submission criteria is that the demo repository must include sufficient documentation to stand up your project after cloning locally. Also the repository must include some kind of explanation or overview of the intent of your project. You can check some examples below. The main reason for explanation is that person who analyzes your repo needs to understand your project. Keep this in mind when preparing the documentation. 

• What is this project about (explain your project in one paragraph)
• Tell us how to clone and build your project
• Explain each function that your contract has and show us how to run them
• Also, show us how to use your scripts

This is a nice example of what it should look like:
