-__Attention MongoDB 3 users:__ In MongoDB 3 the default auth mechanism is ScramSHA1 not MongoCR (the default auth mechanism in mongojs). When connecting to an auth enabled MongoDB 3 instance providing the authMechanism option value 'ScramSHA1' is mandatory!

 After we connected we can query or update the database just how we would using the mongo API with the exception that we use a callback.
 The format for callbacks is always `callback(error, value)` where error is null if no exception has occured. The update methods `save`, `remove`, `update` and `findAndModify` also pass the `lastErrorObject` as the last argument to the callback function.
