I am doing an exercise app about getting grocery delivered to your home.

At this point, I am working on the requirements specifications and the user interface.

I need help the requirements specifications.

The exercise app will be applied to my university neighborhood only.

I need help in determining the functional specifications and the non-functional specifications.

You can see on the attached file that I did some of it, but I am not sure if it is correct or enough.
