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  • ❌ Out-of-date examples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
