Now that we have a clearer view in terms of partnership, I started to write down a list of items that need to be implemented to reach a shippable state.
Phase 1 is everything we absolutely need. And yes, it’s quite a long list Phase 2 will come later, but is useful as a backlog of lower priority items.
