 * 
 * @example

 */
```

### When to Comment

|-----------|-----------------|
| Why (business logic) | What (obvious) |
| Complex algorithms | Every line |
| Non-obvious behavior | Self-explanatory code |
| API contracts | Implementation details |

## 7. Structure Principles

| Principle | Why |
|-----------|-----|
| **Scannable** | Headers, lists, tables |
| **Examples first** | Show, don't just tell |
| **Progressive detail** | Simple → Complex |
| **Up to date** | Outdated = misleading |

---

> **Remember:** Templates are starting points. Adapt to your project's needs.
