+=head1 NAME
+
+Joker - simple OO interface to the Joker domain registry
+
+=head1 SYNOPSIS
+
+ use Joker;
+
+=head1 DESCRIPTION
+
+=head1 CONSTRUCTOR
+
+The B<new> method serves as a constructor. It requires a hash with the
+following attributes:
+
+=over
+
+=item B<username> = I<username>
+
+The username, that is your Joker.com account.
+
+=item B<password> = I<password>
+
+The password for the account above.
+
+=back
+
+Optional attributes are:
+
+=over
+
+=item B<ur> = I<uri of the DMAP server>
+
+The URI where the requests are sent to. (default:
+https://dmapi.ote.joker.com/) For production use remove the "ote" from
+the URI.
+
+=item B<id_file> = I<id file>
+
+The temporary store for the joker auth-id. The first login returns a
+joker auth-id (cookie). This cookie may be reused on further requests
+until it expires. (default: C<$ENV{JOKER_AUTH_ID_FILE}> //
+C<$ENV{HOME}/.joker-auth-id>)
+
+=back
+
+=head1 METHODS
+
+=head2 B<request>(I<request>, I<request params>)
+
+Send a request to the DMAPI. Returns a L<Joker::Result> object. Please
+refer to the L<DMAPI specs|https://dmapi.joker.com/docs/DMAPI-ext.txt>.
