Documentation Best Practices

Write for your audience

• Beginners need more context

• Experts need quick reference

Use consistent formatting

• Same heading styles

• Consistent code block formatting

• Standard terminology

Include examples

• Working code snippets

• Expected outputs

• Common use cases

Keep it updated

• Review with each release

• Mark deprecated features

• Include version information

Make it scannable

• Clear headings

• Bullet points for lists

• Tables for structured data

• TOC for long documents

TypeScript/JavaScript JSDoc

/**

• Calculates the total price including tax.
• @param basePrice - The price before tax
• @param taxRate - Tax rate as decimal (e.g., 0.08 for 8%)
• @returns The total price including tax
• @example
• const total = calculateTotal(100, 0.08);
• console.log(total); // 108

*/ function calculateTotal(basePrice: number, taxRate: number): number { return basePrice * (1 + taxRate); }

Examples

User asks: "Help me write documentation for my API"

Response approach:

• Ask about the API's purpose and target audience

• Identify all endpoints and their methods

• Document request/response formats with examples

• Include authentication requirements

• Add error codes and troubleshooting

• Provide quickstart guide for common operations
