Nested routes in Ember

I want my settings area to look like this:

..
/settings/:accountId/users
/settings/:accountId/users/:userId

I have my router defined as follows:

Router.map(function() {
    this.route('login');
    this.resource('settings', { path: 'settings/:settings_id' }, function() {
        this.route('overview');
        this.route('users');
    });
});

This works for displaying the users listing page. I'm not sure how to take it to the next step though and have both a route and a resource for /users and /users/1.

Thanks.
