+[-t, --enrollment-token <token>] [-s, --silent]
+[-V, --version] [-h, --help]
+```
+
+
+## Description [_description]
+
+Use this command to configure a secure connection between {{kib}} and {{es}}. The tool guides you through the process of enrolling {{kib}} with a secured {{es}} cluster using an enrollment token. This is particularly useful for initial setup and configuration of {{kib}} in secured environments.
+
+::::{important}
+You must have an enrollment token generated from your {{es}} cluster before running this command.
+::::
+
+
+
+## Parameters [kibana-setup-parameters]
+
+`-t, --enrollment-token <token>`

+
+`-V, --version`

+
+
+## Examples [_examples_2]
+
+The following command runs the interactive setup process:
+
+```shell
+bin/kibana-setup
+```
+
+The following command configures {{kib}} with a specific enrollment token:
+
+```shell
+bin/kibana-setup --enrollment-token <your-enrollment-token>
+```
+
+The following command runs setup silently with an enrollment token:
+
+```shell
+bin/kibana-setup --enrollment-token <your-enrollment-token> --silent
+```
