+#     This script enrolls Elastic Agent with Elastic Fleet Server if Elastic Agent is installed, the `ELASTIC_TOKEN` is provided, and the
+#     `elastic_fleet_server` is defined.
+#
+#     Fleet provides a web-based UI in Kibana for centrally managing Elastic Agents and their policies. Fleet Server is the mechanism
+#     to connect Elastic Agents to Fleet. All communication between the Fleet UI and Fleet Server happens through Elasticsearch.
+#
+#     [Integrations](https://www.elastic.co/guide/en/fleet/current/integrations.html) and [Policies](https://www.elastic.co/guide/en/fleet/current/agent-policy.html)
+#     are configured using Fleet UI in Kibana. The [enrollment-token](https://www.elastic.co/guide/en/fleet/current/install-fleet-managed-elastic-agent.html)
+#     can be obtained from Fleet UI, and, one token can be used to add multiple agents to the corresponding policy.
