Where to locate Onepager/Design Docs?

[ahgraber]

@eugeneyan - this is a great outline and I can see it being very useful for defining our work. Do you have recommendations for how to save/share these?

On one hand, drafting in an enterprise-y Word-type application means it's easy to share via application/email, and all non-technical stakeholders can read.
On the other hand, these documents are strongly linked to project documentation, so I'd be inclined to include in git repo (as markdown?) so history is version controlled and changes can be tracked.

Do you have thoughts or recommendations on this issue? Thank you!
