 ~> For Deploying AS3 JSON in Per-App mode, this resource provided with a attribute [tenant_name](#tenant_name) to be passed to add application on specified tenant, else random tenant name will be generated.
 
 
+As3 Declaration can be deployed in Traditional way as well as Per-Application Way : 
+
+- Traditional Way - Entire Declaration needs to be passed in during the create and update call along with the tenant details in the declaration.
+- Per-Application Way - Only Specific application/s details needs to be passed and rest application can be added in the update call , without passing the entire declaration. Tenant name needs to be passed else random tenant name will be generated.  PerApplication needs to be turned `true` as a Prerequisite on the Big-IP (BIG-IP AS3 version >3.50) device.

+
+on running above 2 resources , we will be able to deploy Applications - `path_app1 , path_app2` on Tenant `Test`
+now, if we run `terraform destroy -target=bigip_as3.as3-example2` , only `path_app2` will be deleted from Tenant.
