-## Elastic support for EDOT SDKs
+## Support for EDOT SDKs
 
 Elastic provides technical support for EDOT Language SDKs according to Elastic's [Support Policy](https://www.elastic.co/support_policy). EDOT SDKs are meant to be used in combination with the [EDOT Collector](/reference/edot-collector/index.md) or the [{{motlp}}](/reference/motlp.md) to ingest data into Elastic solutions from the EDOT SDKs. Other ingestion paths are not officially supported by Elastic.
