+Nova-net Support
+================
+
+The Openstack plugin includes support for Nova-net mode -
+i.e. an Openstack installation which does not have the Networking API
+(Neutron service).
+
+In such an environment, there is but a single preconfigured private network,
+which all servers make use of automatically.
+There are no subnets, networks, routers or ports.
+Since these resource types don't exist,
+the plugin's equivalent types aren't valid to use in such an environment.
+
+There are, however, some resource types whose API is available via both the Nova and Neutron services - These had originally been on the Nova service,
+and later were moved and got extended implementation in the Neutron one,
+but were also kept in the Nova service for backward compatibility.
+
+For these resource types, the Openstack plugin defines two separate types - one in the plugin's standard types namespace (``cloudify.openstack.nodes.XXX``),
+which uses the newer and extended API via the Neutron service;
+and Another in a special namespace (``cloudify.openstack.nova_net.nodes.XXX``),
+which uses the older API via the Nova service.
+This is why you may notice two separate types defined for [Floating](#cloudifyopenstacknodesfloatingip) [IP](#cloudifyopenstacknovanetnodesfloatingip),
+as well as for [Security](#cloudifyopenstacknodessecuritygroup) [Group](#cloudifyopenstacknovanetnodessecuritygroup).
+
+
+To summarize, ensure that when working in a Nova-net Openstack environment,
+Neutron types aren't used - these include all types whose resources' APIs are natively available only via the Network API,
+as well as the types which are in the ``cloudify.openstack.nova_net.Nodes`` namespace.
+
+On the opposite side, when using an Openstack environment which supports Neutron,
+it's recommended to use the Neutron-versions of the relevant types
+(i.e. avoid any types defined under the
+``cloudify.openstack.nova_net.Nodes`` namespace),
+as they offer more advanced capabilities.
+However, it's important to mention that this is not required,
+and using the Nova-versions of some types in a Neutron-enabled environment is possible and will work as well.
