+=head1 NAME
+
+Catalyst::Action::Deserialize - Deserialize Data in a Request
+
+=head1 SYNOPSIS
+
+    package Foo::Controller::Bar;
+
+    __PACKAGE__->config(
+        'default'   => 'text/x-yaml',
+        'stash_key' => 'rest',
+        'map'       => {
+            'text/x-yaml'        => 'YAML',
+            'text/x-data-dumper' => [ 'Data::Serializer', 'Data::Dumper' ],
+        },
+    );
+
+    sub begin :ActionClass('Deserialize') {}
+
+=head1 DESCRIPTION
+
+This action will deserialize HTTP POST, PUT, and OPTIONS 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.
+
+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>.
+
+The results of your Deserializing will wind up in $c->req->data.
+This is done through the magic of L<Catalyst::Request::REST>.
+
+While it is common for this Action to be called globally as a
+C<begin> method, there is nothing stopping you from using it on a
+single routine:
+
+   sub foo :Local :Action('Deserialize') {}
+
+Will work just fine.
+
+When you use this module, the request class will be changed to
+L<Catalyst::Request::REST>.
+
+=head1 SEE ALSO
+
+You likely want to look at L<Catalyst::Controller::REST>, which implements
+a sensible set of defaults for a controller doing REST.
