Plan:FY18-19/1

Outcome:	Engineers have a clear understanding of our technology stack and the plan to better scale, maintain and test it

Target Description	Measurement Method
WMF Staff and volunteers can view and understand the current architecture, proposed architecture, implementation plan as well as the parser unification plan	Ensure the architecture and plan documents exists, are publicly accessible, and are announced on public communication channels
Engineers can confidently port specific individual components of Parsoid and verity its correctness and performance without requiring a full port to be ready	Ensure that token transformers and DOM passes have unit tests and a unit testing framework with suitable mocks
