+==========
+
+The [APM Server][1] receives data from [APM agents][2] and transforms them into
+Elasticsearch documents. It does this by exposing an HTTP server endpoint to
+which agents stream the APM data they collect. After the APM Server has
+validated and processed events from the APM agents, the server transforms the
+data into Elasticsearch documents and stores them in corresponding
+Elasticsearch indices.
+
+The APM Server works in conjunction with APM agents, Elasticsearch, and Kibana.
+Please view the APM Overview for details on how these components work together.

-[Elastic APM][1] is an application performance monitoring system built on the
-Elastic Stack. It allows you to monitor software services and applications in
-real time, collecting detailed performance information on response time for
-incoming requests, database queries, calls to caches, external HTTP requests,
-etc. This makes it easier to pinpoint and fix performance problems quickly.
-
-Elastic APM also automatically collects unhandled errors and exceptions. Errors
-are grouped based primarily on the stacktrace, so you can identify new errors
-as they appear and keep an eye on how many times specific errors happen.
