}
```

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 {

                .<CrawlerClientFactory> singleton("clientFactory", CrawlerClientFactory.class, factory -> {
                    factory.addClient("http:.*", container.getComponent("httpClient"));
                    factory.addClient("file:.*", container.getComponent("fsClient"));
                })
                .singleton("tikaExtractor", TikaExtractor.class)
