Add project scope

[fulldecent]

Please state the goals of this project.

Is this intended to develop a reference implementation?

A reference implementation is created differently than a non-reference implementation. For one, a reference implementation does not add opinionated features

Knowing if this is a reference implementation will help contributors to contribute to this project.
