        $etcd = Etcd3->new(); # host: 127.0.0.1 port: 2379
        $etcd = Etcd3->new({ host => $host, port => $port, ssl => 1 });

        # put key
        $result = $etcd->put({ key =>'foo1', value => 'bar' });

        # get single key
        $key = $etcd->range({ key =>'test0' });

        # return single key value or the first in a list.
        $key->get_value

        # get range of keys
        $range = $etcd->range({ key =>'test0', range_end => 'test100' });

        # return array { key => value } pairs from range request.
        my @users = $range->all

        # watch key range, streaming.
        $watch = $etcd->watch( { key => 'foo', range_end => 'fop'}, sub {
            my ($result) =  @_;
            print STDERR Dumper($result);
        })->create;

        # create/grant 20 second lease
        $etcd->lease( { ID => 7587821338341002662, TTL => 20 } )->grant;

        # attach lease to put
        $etcd->put( { key => 'foo2', value => 'bar2', lease => 7587821338341002662 } );
