 ## Argument Reference
 
+The following arguments are supported:
+
 * `name` - (Required) The name of the bucket.
 * `predefined_acl` - (Optional, Default: 'private') The [canned GCS ACL](https://cloud.google.com/storage/docs/access-control#predefined-acl) to apply.
 * `location` - (Optional, Default: 'US') The [GCS location](https://cloud.google.com/storage/docs/bucket-locations) 
 * `force_destroy` - (Optional, Default: false) When deleting a bucket, this boolean option will delete all contained objects. If you try to delete a bucket that contains objects, Terraform will fail that run. 
+
+The optional `website` block supports:
+
+* `main_page_suffix` - (Optional) Behaves as the bucket's directory index where missing objects are treated as potential directories.
+* `not_found_page` - (Optional) The custom object to return when a requested resource is not found.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `self_link` - The URI of the created resource.
