 Overview and pre-requisites
 
     This is a Quantum plugin that can talk to a set of NVP controllers and
-    implements the core Quantum L2 api.  In order to use it you must have
+    implements the core Quantum v2 api.  In order to use it you must have
     Nicira NVP running and configured.  You must also have Quantum installed
     and configured.
 
-Installation and Configuration
+NVP Plugin configuration
 
-    Edit nvp.ini to match your controller configuration and then modify your
-    Quantum plugins.ini provider path:
+    1) Database configuration
+    The NVP plugin leverages the Quantum database. The following connection
+    parameters should be specified:
+    - sql_connection: Database connection string
+    - sql_max_retries: Maximum number of connection attempts (default 10)
+    - reconnect_interval: Gap between connection attempts (default 2 seconds)
+    2) NVP (general)
+    - max_lp_per_bridged_ls: Maximum number of ports of a logical switch on a
+    bridged transport zone (default 64)
+    - concurrent_connections: Number of connects to each controller node
+    (default 3)
+    - failover_time: Time from when a connection pool is switched to another
+    controller during failures.
+    3) NVP cluster
+    The Quantum NVP plugin allow for configuring multiple clusters.
+    Each cluster configuration section must be declared in the following way
+    in the configuration file: [CLUSTER:cluster_name].
+    The following parameters can be configured for each cluster:
+    - default_tz_uuid: This is uuid of the default NVP Transport zone that
+    will be used for creating tunneled isolated "Quantum" networks. It
+    needs to be created in NVP before starting Quantum with the nvp plugin.
+        - nova_zone_id: Optional parameter identifying the Nova "zone" that maps
+        to this NVP cluster.
+        - nvp_cluster_uuid: Optional paramter identifying the UUID of the cluster
+        in NVP.  This can be retrieved from NVP management console "admin" section.
+        - nvp_controller_connetion: describes a connection to a single NVP
+        controller. A different connection for each controller in the cluster can
+        be specified; there must be at least one connection per cluster.
 
-    provider = quantum.plugins.nicira.nicira_nvp_plugin.QuantumPlugin.NvpPlugin
+Quantum Configuration
 
-Testing
+    Modify your Quantum configuration for using the NVP Plugin:
 
-    Edit etc/quantum/plugins/nicira/nvp.ini to match your nvp configuration
-    (nvp must be up and running). Then:
+    core_plugin =
+        quantum.plugins.nicira.nicira_nvp_plugin.QuantumPlugin.NvpPluginV2
 
-    $ cd quantum/plugins/nicira
