+QR queues store serialized Python objects (using [cPickle](http://docs.python.org/library/pickle.html) by default), but that can be changed by
 setting the serializer on a per-queue basis.  This means "Python object in, and Python object out." There are a few constraints
 on what can be pickled, and thus put into queues:

 -------------------------------------
 
 QR contains a few small classes to represent each data structure. To get access to one of the data structures, you create an instance. You can pass custom options for the underlying Redis instance as keyword arguments. For example:
 
 ```python
+from qr3.qr import Queue
+
 Queue('brand_new_queue_name', host='localhost', port=9000)
