Writing Guidelines

Clarity

• Use simple, direct language
• One concept per paragraph
• Active voice preferred

Structure

• Start with overview
• Progress from simple to complex
• Include code examples

Accuracy

• Verify all code samples work
• Keep versions up to date
• Link to authoritative sources

Completeness

• Cover common use cases
• Include error handling
• Document edge cases

Code Example Standards

Do

// Good: Clear, runnable example
import { Client } from 'library';

const client = new Client({ apiKey: process.env.API_KEY });
const result = await client.getData();
console.log(result);

Don't

// Bad: Incomplete, unclear
const x = new X();
x.y(); // does stuff
