 =head1 DESCRIPTION
 
-This action will deserialize HTTP POST, PUT, and OPTIONS requests.
+This action will deserialize HTTP POST, PUT, OPTIONS and DELETE requests.
 It assumes that the body of the HTTP Request is a serialized object.
 The serializer is selected by introspecting the requests content-type
 header.
 
+If you want deserialize any other HTTP method besides POST, PUT,
+OPTIONS and DELETE you can do this by setting the
+C<< deserialize_http_methods >> list via C<< action_args >>.
+Just modify the config in your controller and define a list of HTTP
+methods the deserialization should happen for:
+
+    __PACKAGE__->config(
+        action_args => {
+            '*' => {
+                deserialize_http_methods => [qw(POST PUT OPTIONS DELETE GET)]
+            }
+        }
+    );
+
+See also L<Catalyst::Controller/action_args>.
+
 The specifics of deserializing each content-type is implemented as
 a plugin to L<Catalyst::Action::Deserialize>.  You can see a list
 of currently implemented plugins in L<Catalyst::Controller::REST>.

+For building custom error responses when de-serialization fails, you can create
