One paragraph explanation of the change.

Motivation

Why are we doing this? What use cases does it support? What problems does it solve? What is the expected outcome?

Design Details

This is the bulk of the RFD.

Introduce and explain new concepts. It should be reasonably clear how the proposal would be implemented. Provide representative examples that show how this proposal would be commonly used. Corner cases should be dissected by example.

Drawbacks

Why should we not do this?

Rationale and Alternatives

This is your chance to discuss your proposal in the context of the whole design space. This is probably the most important section! Why is this design the best in the space of possible designs? What other designs have been considered and what is the rationale for not choosing them? What is the impact of not doing this?

Unresolved issues

What parts of the design do you expect to resolve through the RFD process before this gets merged?

What parts of the design do you expect to resolve through the implementation of this feature?

What related issues do you consider out of scope for this RFD that could be addressed in the future independently of the solution that comes out of this RFD?
