 ## Notes
 
-* `network_interface` can't be specified together with `vpc_security_group_ids`, `associate_public_ip_address`, `subnet_id`. See [basic example](https://github.com/terraform-aws-modules/terraform-aws-ec2-instance/tree/master/examples/basic) for details. 
-* Changes in `ebs_block_device` argument will be ignored. Use [aws_volume_attachment](https://www.terraform.io/docs/providers/aws/r/volume_attachment.html) resource to attach and detach volumes from AWS EC2 instances. See [this example](https://github.com/terraform-aws-modules/terraform-aws-ec2-instance/tree/master/examples/volume-attachment).
-* One of `subnet_id` or `subnet_ids` is required. If both are provided, the value of `subnet_id` is prepended to the value of `subnet_ids`.
