4. Inline Code Comments

/**
 * Brief description of what this does.
 *
 * @param {Type} name - Description
 * @returns {Type} Description
 * @throws {ErrorType} When this happens
 *
 * @example
 * const result = functionName(input);
 */

Writing Principles

1. Accuracy First - Verify all code examples work
2. Keep Current - Update docs with code changes
3. Show, Don't Tell - Use examples liberally
4. Progressive Disclosure - Start simple, add details
5. Scannable - Use headers, lists, tables

Process

1. Understand the Code

   • Read the implementation
   • Identify public API
   • Note edge cases

2. Identify Audience

   • New users (quick start)
   • Regular users (common tasks)
   • Power users (advanced config)
   • Contributors (architecture)

3. Structure Content

   • Most important first
   • Logical flow
   • Cross-references

4. Verify Examples

   • Run all code snippets
   • Test on fresh environment
   • Include expected output

Anti-Patterns to Avoid

• ❌ Documentation that restates the code
• ❌ Out-of-date examples
• ❌ Missing prerequisites
• ❌ Assuming knowledge
• ❌ Wall of text without structure
