-Provides a Direct Connect LAG.
+Provides a Direct Connect LAG. Connections can be added to the LAG via the [`aws_dx_connection`](/docs/providers/aws/r/dx_connection.html) and [`aws_dx_connection_association`](/docs/providers/aws/r/dx_connection_association.html) resources.
+
+~> *NOTE:* When creating a LAG, Direct Connect requires creating a Connection. Terraform will remove this unmanaged connection during resource creation.

 * `location` - (Required) The AWS Direct Connect location in which the LAG should be allocated. See [DescribeLocations](https://docs.aws.amazon.com/directconnect/latest/APIReference/API_DescribeLocations.html) for the list of AWS Direct Connect locations. Use `locationCode`.
-* `number_of_connections` - (**Deprecated**) The number of physical connections initially provisioned and bundled by the LAG. Use `aws_dx_connection` and `aws_dx_connection_association` resources instead. Default connections will be removed as part of LAG creation automatically in future versions.
 * `force_destroy` - (Optional, Default:false) A boolean that indicates all connections associated with the LAG should be deleted so that the LAG can be destroyed without error. These objects are *not* recoverable.
 * `tags` - (Optional) A mapping of tags to assign to the resource.
