## Files to Create
- `docs/README.md` (main documentation index)

## Priority: Medium
Important for user adoption and project sustainability.

Start by auditing the existing project to determine which major features and documentation already exist, then review the proposed structure: docs/README.md, docs/API_REFERENCE.md, docs/USER_GUIDE.md, docs/DEVELOPER_GUIDE.md, docs/CULTURAL_GUIDE.md, and docs/TUTORIALS/. Done means the requested technical, user, developer, and cultural materials are accurate, organized, accessible, and cover the stated success criteria.
