+== Terms of use
+
+Customers may add third party trained models for management in Elastic. These 
+models are not owned by Elastic. Customers must contract separately with the 
+third party model owner for the use of the model, and such use will be governed 
+by the applicable terms and conditions. You understand and agree that Elastic 
+has no control over, or liability for, the third party models.
