 ClickStack provides multiple ways to ingest observability data into your ClickHouse instance. This section contains
 quick start guides for various log and trace sources.
 
+:::note
+Several of these integration guides use ClickStack's built-in OpenTelemetry Collector for quick testing. For production deployments, we recommend running your own OTel Collector and sending data to ClickStack's OTLP endpoint. See [Sending OpenTelemetry data](/use-cases/observability/clickstack/ingesting-data/opentelemetry) for production configuration.
