 ## Argument Reference
 
 The following arguments are supported:
+* `name` (Required) Human friendly name given to the instance group. Changing this forces a new resource to be created.
+* `cluster_id` (Required) ID of the EMR Cluster to attach to. Changing this forces a new resource to be created.
+* `instance_type` (Required) The EC2 instance type for all instances in the instance group. Changing this forces a new resource to be created.
+* `instance_count` (Optional) Target number of instances for the instance group. Defaults to 0.
+* `ebs_optimized` (Optional) Indicates whether an Amazon EBS volume is EBS-optimized. Changing this forces a new resource to be created.
+* `ebs_config` (Optional) One or more `ebs_config` blocks as defined below. Changing this forces a new resource to be created.
 
-* `name` - (Optional) Optional human friendly name for this Instance Group
-* `cluster_id` - (Required) ID of the EMR Cluster to attach to
-* `instance_type` - (Required) Type of instances for this Group
-* `instance_count` - (Optional) Count of instances to launch
+`ebs_config` supports the following:
+* `iops` - (Optional) The number of I/O operations per second (IOPS) that the volume supports.
+* `size` - (Optional) The volume size, in gibibytes (GiB). This can be a number from 1 - 1024. If the volume type is EBS-optimized, the minimum value is 10.
+* `type` - (Optional) The volume type. Valid options are 'gp2', 'io1' and 'standard'.
+* `volumes_per_instance` - (Optional) The number of EBS Volumes to attach per instance.
