-### Importing resources
-
-Currently, only `mongodbatlas_cluster`, `mongodbatlas_database_user`, `mongodbatlas_vpc_peering_connection` and `mongodbatlas_ip_whitelist` can be imported.
-
-To import any of these resources, you need the project ID (aka. group ID). This can be found in the project
-settings screen.
-
-```
-# Import a cluster
-terraform import mongodbatlas_cluster.example <project ID>-<cluster name>
-
-# Import a database user
-# NOTE: you'll see a plan diff for the password, this is unavoidable since the user read API omits it
-terraform import mongodbatlas_database_user.example <project ID>-<username>
-
-# Import an ip whitelist
-terraform import mongodbatlas_ip_whitelist.example <project ID>-<cidr>

-# Import an vpc peering
-# specify the peering connection id( pcx-xxxxxxxxx )
-terrform import mongodbatlas_vpc_peering_connection.example <project ID>-<pcx id>

 make build

-## NOTE
-The `mongodbatlas_container` resource does not destroy the container (vpc) in mongo atlas. This is due to a limitation of the mongo atlas API as it doesn't support deleting this resource.
