+

+    instances = [1]
+    while len(instances) > 0:
+        instances = client.instances.list()
+        for instance in instances:
+            try:
+                instance.delete()
+            except:
+                pass
+
+    flavor_id = "1"
+    for i in range(30):
+        name = "Instance #%d" % i
+        client.instances.create(name, flavor_id, None)
+
+
+
+Authentication
+--------------
+
+Authenticating is necessary to use every feature of the client (except to
+discover available versions).
+
+To create the client, create an instance of the Dbaas (Database as a Service)
+class. The auth url, auth user, key, and tenant ID must be specified in the
+call to the constructor.
+
+.. testcode::
+
+    from reddwarfclient import Dbaas
+    global AUTH_URL
+
+    client = Dbaas("jsmith", "abcdef", tenant="12345",
+                  auth_url=AUTH_URL)
+    client.authenticate()
+
+The default authentication strategy assumes a Keystone complaint auth system.
+For Rackspace auth, use the keyword argument "auth_strategy='rax'".
+
+
+Versions
+--------
+
+You can discover the available versions by querying the versions property as
+follows:
+
+
+.. testcode::
+
+    versions = client.versions.index("http://localhost:8779")
+
+
+The "index" method returns a list of Version objects which have the ID as well
+as a list of links, each with a URL to use to reach that particular version.
+
+.. testcode::
+
+    for version in versions:
+        print(version.id)
+        for link in version.links:
+            if link['rel'] == 'self':
+                print("    %s" % link['href'])
+
+.. testoutput::
+
+    v1.0
+        http://localhost:8779/v1.0
+
+
+Instances
+---------
+
+The following example creates a 512 MB instance with a 1 GB volume:
+
+.. testcode::
+
+    client.authenticate()
+    flavor_id = "1"
+    volume = {'size':1}
+    databases = [{"name": "my_db",
+                  "character_set": "latin2",      # This and the next field are
+                  "collate": "latin2_general_ci"}] # optional.
+    users = [{"name": "jsmith", "password": "12345",
+              "databases": [{"name": "my_db"}]
+             }]
+    instance = client.instances.create("My Instance", flavor_id, volume,
+                                       databases, users)
+
+To retrieve the instance, use the "get" method of "instances":
+
+.. testcode::
+
+    updated_instance = client.instances.get(instance.id)
+    print(updated_instance.name)
+    print("   Status=%s Flavor=%s" %
+              (updated_instance.status, updated_instance.flavor['id']))
+
+.. testoutput::
+
+    My Instance
+       Status=BUILD Flavor=1
+
+You can delete an instance by calling "delete" on the instance object itself,
+or by using the delete method on "instances."
+
+.. testcode::
+
+    # Wait for the instance to be ready before we delete it.
+    import time
+    from reddwarfclient.exceptions import NotFound
+
+    while instance.status == "BUILD":
+        instance.get()
+        time.sleep(1)
+    print("Ready in an %s state." % instance.status)
+    instance.delete()
+    # Delete and wait for the instance to go away.
+    while True:
+        try:
+            instance = client.instances.get(instance.id)
+            assert instance.status == "SHUTDOWN"
+        except NotFound:
+            break
+
+.. testoutput::
+
+    Ready in an ACTIVE state.
+
+
+Listing instances and Pagination
+--------------------------------
+
+To list all instances, use the list method of "instances":
+
+.. testcode::
+
+    instances = client.instances.list()
+
+
+Lists paginate after twenty items, meaning you'll only get twenty items back
+even if there are more. To see the next set of items, send a marker. The marker
+is a key value (in the case of instances, the ID) which is the non-inclusive
+starting point for all returned items.
+
+The lists returned by the client always include a "next" property. This
+can be used as the "marker" argument to get the next section of the list
+back from the server. If no more items are available, then the next property
+is None.
+
+.. testcode::
+
+    # There are currently 30 instances.
+
+    instances = client.instances.list()
+    print(len(instances))
+    print(instances.next is None)
+
+    instances2 = client.instances.list(marker=instances.next)
+    print(len(instances2))
+    print(instances2.next is None)
+
+.. testoutput::
+
+    20
+    False
+    10
+    True
+
