README Guidelines

Each top-level package directory (e.g., plain-api/) has a README.md symlink pointing to the actual README inside the package (e.g., plain-api/plain/api/README.md). Only edit the README inside the package itself.

See `plain-jobs/plain/jobs/README.md` as a good example.

Purpose

The README answers: "How do I use this?" It gets users productive quickly and points them to code for deeper exploration. It is not a complete API reference.

Required Structure

Every README follows this order:

1. h1 with package name
2. Bold one-liner describing the package
3. Table of contents with links to h2s and h3s
4. Overview section with basic working examples
5. Feature sections as needed
6. FAQs section (second to last) using h4s for questions
7. Installation section (always last)

Style

• Conversational tone: "You can..." not "The module provides..."
• First code example must be copy-paste ready with imports included
• Subsequent examples can be minimal, building on what was shown
• Link to source for advanced features: [ClassName](./file.py#ClassName)
• Cross-package references: [plain.auth](../../plain-auth/plain/auth/README.md)

What to Document

• If users import it, document it
• Mention all public features, even advanced ones briefly, then link to code
• Internal APIs stay undocumented (_prefix functions and @internalcode)
• Don't fully document every parameter - mention features exist, link to code

Writing Tips

• Keep paragraphs short
• Put takeaways up front
• Use bullets and tables
• Bold important text
• Keep sentences simple and unambiguous
