+The easiest way to integrate your logs with APM is to use the
+https://github.com/elastic/ecs-logging-python[`ecs-logging`] library, which
+is also provided by Elastic. This library provides formatters for both `logging`
+and `structlog` which create ECS-compatible logs and will include the tracing
+information required for log correlation in kibana. Coupled with something like
+https://www.elastic.co/beats/filebeat[Filebeat], it is the easiest way to get
+logs into Elasticsearch.
