+  description: |
+    This plugin executes application-specific preflight checks and conformance tests against a cluster, prior to installation of an application.
+
+    Application developers can create and host a Preflight manifest that defines the minimum and desired Kubernetes environment
+    for an application. Before installing the application, a cluster admin can use this plugin to execute the application preflight checks
+    to identify any missing components, configuration or incompatibilities between the cluster and the desired environment.
+
+    When executing Preflight tests, the test results will be displayed in a terminal-based UI on the workstation that executed the command.
+
+    For information on creating a Preflight manifest, view the documentation at https://help.replicated.com/docs/troubleshoot/kubernetes/analysis/
