API Documentation

Document as You Build

• Document APIs during development, not after
• Keep documentation in sync with code
• Use real examples over abstract descriptions
• Show both success and error cases
• Version everything including docs

OpenAPI Specification

Structure:

• API metadata (title, version, description)
• Server definitions
• Security schemes
• Paths and operations
• Request/response schemas
• Examples for all operations

Example:

openapi: 3.0.0
info:
  title: User API
  version: 1.0.0
  description: API for user management

paths:
  /users:
    get:
      summary: List users
      responses:
        '200':
          description: List of users
          content:
            application/json:
              schema:
                type: array
                items:
                  $ref: '#/components/schemas/User'

Technical Writing

Write for Your Audience

• Know their skill level
• Use appropriate terminology
• Provide context when needed
• Assume minimal prior knowledge
• Include troubleshooting sections

Lead with the Outcome

• Start with what users will accomplish
• Show the value before the steps
• Use clear, action-oriented language
• Focus on user success, not features

Use Active Voice

Changelog Generation

Transforming Git Commits

Automatically creates user-facing changelogs from git commits by:

• Analyzing commit history
• Categorizing changes (features, improvements, bug fixes, breaking changes, security)
• Transforming technical commits into clear, customer-friendly release notes
• Filtering out internal commits (refactoring, tests, etc.)

Basic Usage
