+Basic Overview
+--------------
+
+The {pve} SDN allows separation and fine grained control of Virtual Guests
+networks, using flexible software controlled configurations.
+
+Separation consists of zones, a zone is it's own virtual separated area.
+A Zone can be used by one or more 'VNets'. A 'VNet' is virtual network in a
+zone. Normally it shows up as a common Linux bridge with either a VLAN or
+'VXLAN' tag, or using layer 3 routing for control.
+The 'VNets' are deployed locally on each node, after configuration was commited
+from the cluster wide datacenter level.
