+## Elastic APM Log Correlation
+
+`ecs-logging-python` supports automatically collecting [ECS tracing fields](https://www.elastic.co/guide/en/ecs/master/ecs-tracing.html)
+from the [Elastic APM Python agent](https://github.com/elastic/apm-agent-python) in order to
+[correlate logs to spans, transactions and traces](https://www.elastic.co/guide/en/apm/agent/python/current/log-correlation.html) in Elastic APM.
