Two questions: Who reads this? then What do they need?
| Audience | Entry Point | Voice | Key Question |
|---|---|---|---|
| Agents | AGENTS.md | Imperative, terse, verifiable | "What do I DO?" |
| Users | README.md | Welcoming, progressive | "How do I USE this?" |
| Maintainers | CONTRIBUTING.md | Technical, explains why | "How do I CHANGE this?" |
Mixing audiences in one document serves neither. Split.
| Mode | Reader State | Structure | Example |
|---|---|---|---|
| Learning (tutorial) | Beginner | Numbered steps, verify each | "Build your first widget" |
| Doing (how-to) | Has a problem | Goal → steps → done | "How to configure auth" |
| Looking up (reference) | Needs a fact NOW | Tables, alphabetical | CLI flags, API reference |
| Understanding (explanation) | Curious, has time | Prose, diagrams, tradeoffs | "Why event sourcing" |
| Type | Path | Litmus Test |
|---|---|---|
| Decision (ADR) | decisions/ | "What did we decide and why?" |
| Specification | specs/ | "What must the system do?" |
| User guide | top-level or guides/ | "How does a user do this?" |
| Architecture | architecture/ | "How is it structured?" |
| Research | research/ | "What did we learn?" |
| Runbook | runbooks/ | "What steps fix this?" |
Before placing: check existing folder conventions first. Match what's there.
| Project Maturity | Required Docs |
