If there are related problems that you have decided not to address with this design, but which someone might conceivably expect you to solve, then list them here.

Start with a brief, high-level description of the solution. The following sections will go into more detail.

If the design consists of a collaboration between multiple large-scale components, list those components here — or better, include a diagram.

Describe how the data is stored. This could include a description of the database schema.

Describe how the various components talk to each other. For example, if there are REST endpoints, describe the endpoint URL and the format of the data and parameters used.

If the design requires any non-trivial algorithms or logic, describe them.
