Title: Callback URL doesn't exist

There seems to be a typo in the Usage Example. The callback URL is set for "account/services/callback/'.$provider->name" which doesn't exist if you're only following this example. I suppose you could probably set this as an alias in routes.php, but the readme makes no mention of that.
