+
+## Example Usage
+
+```
+data "kubernetes_storage_class" "example" {
+  metadata {
+    name = "terraform-example"
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `metadata` - (Required) Standard storage class's metadata. More info: https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md#metadata
+
+
+## Nested Blocks
+
+### `metadata`
+
+#### Arguments
+
+* `name` - (Required) Name of the storage class, must be unique. More info: http://kubernetes.io/docs/user-guide/identifiers#names
+
+#### Attributes
+
+
+* `generation` - A sequence number representing a specific generation of the desired state.
+* `resource_version` - An opaque value that represents the internal version of this storage class that can be used by clients to determine when storage class has changed. Read more: https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md#concurrency-control-and-consistency
+* `self_link` - A URL representing this storage class.
+* `uid` - The unique in time and space value for this storage class. More info: http://kubernetes.io/docs/user-guide/identifiers#uids
+
+
+## Argument Reference
+
+The following attributes are exported:
+
+* `parameters` - The parameters for the provisioner that creates volume of this storage class.
+	Read more about [available parameters](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#parameters).
+* `storage_provisioner` - Indicates the type of the provisioner this storage class represents
