+Accessing the cache
+-------------------
+
 The cache module, ``django.core.cache``, has a ``cache`` object that's
 automatically created from the ``'default'`` entry in the :setting:`CACHES`
 setting::
 
     >>> from django.core.cache import cache
 
+If you have multiple caches defined in :setting:`CACHES`, then you can use
+:func:`django.core.cache.get_cache` to retrieve a cache object for any key::
+
+    >>> from django.core.cache import get_cache
+    >>> cache = get_cache('alternate')
+
+If the named key does not exist, :exc:`InvalidCacheBackendError` will be raised.
+
+
+Basic usage
+-----------
+
 The basic interface is ``set(key, value, timeout)`` and ``get(key)``::
 
     >>> cache.set('my_key', 'hello, world!', 30)
