A README.md that covers:

• Deployment - that covers how to build and test your submission.
• Configuration - make sure to document the configuration that are used by the submission.
• Dependency installation -  should clearly describe the step-by-step guide for installing dependencies and should be up to date.

A Validation.md that covers:
Validation of each requirement can be mentioned in this document which will be easier for reviewers to map the requirements with your submission.

Final Submission Guidelines

• Java project source code
• Submit all the SQL scripts.
• Make sure to document the class and methods of the source files following the best practices. There should not be any warnings from Java compiler.
