I am not seeking a formal design document for your project as the focus is more on the construction phase of the project. At a minimal, I would like you to include a software architecture design describing the major components of your software project and the relationship between them and low-level design  (like a class diagram) detailing the design details at the lower level of granularity. Make sure to include appropriate design diagrams in your document. The entire document need not be over 4 – 7 pages.
