## When to Use Me

Use me when:
- Starting a new project
- Writing API documentation
- Creating user guides
- Documenting architecture
- Preparing for releases
- Onboarding team members

## My Technology Stack

- **API Docs**: OpenAPI 3.1, Swagger UI, ReDoc
- **Diagrams**: Mermaid, PlantUML, C4 model
- **Docs Platform**: Markdown, Docusaurus, GitBook
- **Code Docs**: JSDoc, Sphinx, rustdoc

## Documentation Strategy

### API Documentation

**Format: OpenAPI 3.1**

```yaml
openapi: 3.1.0
info:
  title: E-Commerce API
  version: 1.0.0
  description: REST API for e-commerce platform

paths:
  /api/products/{id}:
    get:
      summary: Get product by ID
      parameters:
        - name: id
          in: path
          required: true
          schema:
            type: string
            format: uuid
      responses:
        '200':
          description: Product found
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Product'
              example:
                id: "123e4567-e89b-12d3-a456-426614174000"
                name: "Laptop"
                price: 999.99
        '404':
          description: Product not found
```

**Hosting:**
- Swagger UI for interactive testing
- ReDoc for beautiful static docs
- Versioned (v1, v2, etc.)

### Architecture Documentation

**C4 Model:**

**Level 1: Context**
- System in environment
- External users and systems
- High-level interactions

**Level 2: Containers**
- Major components (frontend, backend, database)
- Communication protocols
- Responsibilities

**Level 3: Components**
- Internal structure
- Major classes/modules
- Dependencies

**Level 4: Code**
- Class diagrams
- Sequence diagrams
- Implementation details

**ADR Template:**
```markdown
# ADR-001: Use Microservices Architecture

## Status
Accepted

## Context
Building e-commerce platform with 10K concurrent users

## Decision
Use microservices architecture with event-driven communication

## Consequences
**Positive:**
- Independent service scaling
- Technology flexibility

**Negative:**
- Increased operational complexity

**Mitigation:**
- Use Kubernetes
- Implement saga pattern
```

### User Documentation

**Getting Started:**
1. Sign up process
2. First-time setup
3. Basic workflows
4. Video tutorials

**Feature Guides:**
- Step-by-step instructions
- Screenshots for each step
- Expected outcomes
- Troubleshooting tips

**FAQ:**
- Common questions grouped by topic
- Clear, concise answers
- Links to detailed guides

### Operational Documentation

**Runbooks:**

**Incident Response:**
```yaml
high_error_rate:
  steps:
    - Check monitoring dashboard
    - Identify failing service
    - Check recent deployments
    - Rollback if needed
    - Investigate root cause
    - Update postmortem

database_connection_pool_exhausted:
  steps:
    - Check active connections
    - Identify long-running queries
    - Kill problematic queries
    - Increase pool size if needed
```

**Maintenance Procedures:**
- Daily: Review logs, check backups
- Weekly: Update dependencies, clean worktrees
- Monthly: Review metrics, optimize costs
- Quarterly: Security audit, performance review

## Best Practices

When working with me:
1. **Document as you code** - Don't wait until the end
2. **Keep it current** - Outdated docs are worse than no docs
3. **Be specific** - Examples are worth 1000 words
4. **Know your audience** - User docs vs. developer docs
5. **Make it searchable** - Good structure and navigation
