+description: |
+  Principal charm that deploys ovn-northd, the OVN central control daemon,
+  and ovsdb-server, the Open vSwitch Database (OVSDB).
+
+  The ovn-northd daemon is responsible for translating the high-level OVN
+  configuration into logical configuration consumable by daemons such as
+  ovn-controller.
+  
+  The ovn-northd process talks to OVN Northbound- and Southbound- databases.
+
+  The ovsdb-server exposes endpoints over relations implemented by the ovsdb
+  interface.
+
+  The charm supports clustering of the OVSDB, you must have a odd number of
+  units for this to work. Note that write performance decreases as you
+  increase the number of units.
+  
+  Running multiple ovn-northd daemons is supported and they will operate in
+  active/passive mode. The daemon uses a locking feature in the OVSDB to
+  automatically choose a single active instance.
