Writing Guidelines

Clarity and Structure

Use Clear Headings

• •Hierarchical structure (H1 → H2 → H3)
• •Descriptive and specific titles
• •Consistent formatting

Write Scannable Content

• •Use bullet points and numbered lists
• •Break up long paragraphs
• •Highlight key information
• •Use tables for structured data

Provide Context

• •Explain why, not just how
• •Include prerequisites
• •Define technical terms
• •Link to related concepts

Code Documentation

Code Examples

• •Include complete, runnable examples
• •Show both input and output
• •Cover common use cases
• •Test all examples for accuracy

Inline Comments

// Good: Explains why, not what
const delay = 1000; // Wait time for API rate limiting

// Poor: Explains what code does
const delay = 1000; // Set delay to 1000

API Documentation

• •Document all public methods
• •Include parameter types and descriptions
• •Show example usage
• •Document exceptions and edge cases

Visual Elements

Diagrams and Charts

• •Use for complex concepts
• •Keep diagrams simple and focused
• •Include alt text for accessibility
• •Use consistent styling

Screenshots

• •Show actual interface elements
• •Highlight relevant areas
• •Keep images current
• •Use callouts for clarity

Code Formatting

• •Use syntax highlighting
• •Consistent indentation
• •Show file structure with trees
• •Use fenced code blocks

Content Organization

Information Architecture

Progressive Disclosure

1. •Overview: High-level concept
2. •Quick Start: Basic example
3. •Detailed Guide: Comprehensive coverage
4. •Reference: Complete specification

Logical Grouping

• •Group related concepts together
• •Use consistent navigation patterns
• •Provide clear pathways between sections
• •Include cross-references

Navigation

Table of Contents
