What should we build?

Investigate and document integration of WFO with NSI. The use case is to avoid that NSI endpoints configure directly Network devices without this being tracked in WFO.

Things we could/should do:

• Collect documentation for NSI in a a central location with a good narrative
• Add multi-domain description page in workfloworchestrator.org (this might be the same as previous point)
