2. **Register in DI config** (`crawler.xml`):
```xml
<component name="myClient" class="...MyClient" instance="singleton"/>
```

3. **Add to factory**:
```java
clientFactory.addClient("^myprotocol://.*", myClient);
```

4. **Add tests**: Unit + integration

### Adding a Content Extractor

1. **Implement `Extractor`**:
```java
public class MyExtractor extends AbstractExtractor {
