Good documentation explains why, not just what. AI can generate comprehensive documentation quickly, but you need to prompt it to include the context that makes docs actually useful.

README Generator

Complete README with all essential sections.

Generate a README.md for this project:

Project name: [NAME]
What it does: [ONE SENTENCE]
Tech stack: [LANGUAGES/FRAMEWORKS]

Include these sections:
1. One-paragraph description (what problem it solves, for whom)
2. Quick Start (get running in under 5 commands)
3. Key features (bullet list, 5-8 features)
4. Project structure (tree diagram of important directories)
5. Environment variables (table: name, description, required?, example)
6. API endpoints (if applicable: method, path, description)
7. Contributing (how to set up dev environment, run tests, submit PRs)
8. License

Tone: friendly but professional. No fluff.

API Documentation

Complete API endpoint documentation from code.

Document this API endpoint:

```
[PASTE ROUTE HANDLER CODE]
```

Generate documentation including:
- Endpoint: METHOD /path
- Description: What it does (1-2 sentences)
- Authentication: Required? What type?
- Request: Headers, body (with TypeScript interface), query params
- Response: Success (with example JSON), Error cases (status codes + messages)
- Example: curl command
- Notes: Rate limits, pagination, edge cases
