 ==================================================================
 
-By default, all telemetry is sent to the local instance of the Splunk Distribution of OpenTelemetry Collector.
+By default, all telemetry is sent to the local OpenTelemetry Collector before being forwarded to Splunk Observability Cloud.
+It is also possible to send data directly to Splunk Observability Cloud without using the OpenTelemetry Collector.
+.. note:: Sending data directly to Splunk Observability Cloud is supported only for traces and metrics. Logs cannot be sent using this method.
