Baseline expects a directory contract and a head placeholder, and a project that already exists has its own answers to both. These guides work through the reconciliation one starter at a time: what moves, what gets deleted, and what you keep.

Each one names the version it was written against. Starters move, and a guide that does not say when it was true is worse than no guide.
