Begin with a one sentence Problem Statement and continue with a two-three sentence description of what your project does to address the problem (the Proposed Solution). Follow the Proposed Solution with a bulleted list of Requirements. Then describe in paragraph form, the features from the original assignment that your team has implemented. Each section should be clearly delineated from the other sections.
Describe how you have met the specific requirements of the project (namely, how it is educational, and which 2 data structures you used) .
Start a new paragraph with a Statement of Proposed Enhancement (if you have made any enhancements). Then discuss the extra features you have implemented. Then discuss any planned features that you have not yet implemented (in other words, those that you'd like to have, but didn't get to do). It should be very clear which features you have implemented and which you have not.
Note that all these features (proposed, completed, partially completed) should closely align with the information in your Iterative Enhancement Plan and UML diagram.
