+### Enable Elasticsearch's API key service
+
+Enterprise Search requires Elasticsearch's built-in [API key service][es-security] to be enabled in order to start.
+Unless Elasticsearch is configured to enable TLS on the HTTP interface (disabled by default), this service is disabled
+by default.
+
+To enable it, modify the Elasticsearch configuration file in [`elasticsearch/config/elasticsearch.yml`][config-es] and
+add the following setting:
+
+```yaml
+xpack.security.authc.api_key.enabled: true
+```
+
 ### Start the server
 
 To include Enterprise Search in the stack, run Docker Compose from the root of the repository with an additional command
