Very broadly, describe how the system meets a need of a business, group, the OpenACS as a whole, etc. Make sure that technical and non-technical readers alike would understand what the system would do and why it's useful. Whenever applicable, you should explicitly state what the business value of the system is. -
Discuss the high-level breakdown of the components that make up the system. You can go by functional areas, by the main transactions the system allows, etc.
You should also state the context and dependencies of the system here, e.g. if it's an application-level package for OpenACS 4, briefly describe how it uses kernel services, like permissions or subsites. -
Determine the types or classes of users who would use the system, and what their experience would be like at a high-level. Sketch what their experience would be like and what actions they would take, and how the system would support them. -
Describe other systems or services that are comparable to what you're building. If applicable, say why your implementation will be superior, where it will match the competition, and where/why it will lack existing best-of-breed capabilities. This section is also in the Design doc, so write about it where you deem most appropriate. -

The main course of the document, requirements. Break up the requirements sections (A, B, C, etc.) as needed. Within each section, create a list denominated with unique identifiers that reflect any functional hierarchy present, e.g. 20.5.13. - for the first number, leave generous gaps on the first writing of requirements (e.g. 1, 10, 20, 30, 40, etc.) because you'll want to leave room for any missing key requirements that may arise. -

Although in theory coding comes after design, which comes after requirements, we do not, and perhaps should not, always follow such a rigid process (a.k.a. the waterfall lifecyle). Often, there is a pre-existing system or prototype first, and thus you may want to write some thoughts on implementation, for aiding and guiding yourself or other programmers. -
