 ## Networks
 
-Networking features in the form of `config.vm.network` are not supported right
-now. Support for private network is planned to be added in next release of
-provider.
+Networking features in the form of `config.vm.network` support private networks
+concept. No public network or port forwarding are supported in current version
+of provider.
+
+An examples of network interface definitions:
+
+```ruby
+  config.vm.define :test_vm1 do |test_vm1|
+    test_vm1.vm.network :private_network, :ip => '10.20.30.40'
+  end
+```
+
+In example below, one network interface is configured for VM test_vm1. After
+you run `vagrant up`, VM will be accessible on IP address 10.20.30.40. So if
+you install a web server via provisioner, you will be able to access your
+testing server on http://10.20.30.40 URL. But beware that this address is
+private to libvirt host only. It's not visible outside of the hypervisor box.
+
+If network 10.20.30.0/24 doesn't exist, provider will create it. By default
+created networks are NATed to outside world, so your VM will be able to connect
+to the internet (if hypervisor can). And by default, DHCP is offering addresses
+on newly created networks.
+
+### Private Network Options
+
+There is a way to pass specific options for libvirt provider when using
+`config.vm.network` to configure new network interface. Each parameter name
+starts with 'libvirt__' string. Here is a list of those options:
+
+* `:libvirt__network_name` - Name of libvirt network to connect to. By default,
+  network 'default' is used.
+* `:libvirt__netmask` - Used only together with `:ip` option. Default is
+  '255.255.255.0'.
+* `:libvirt__nat_interface` - Name of interface, where should network be
+  NATed. Used only when creating new network. By default, all physical
+  interfaces are used.
+* `:libvirt__isolated` - If network should be isolated - without NAT to outside.
+  Used only when creating new network. Default is set to false.
+* `:libvirt__dhcp_enabled` - If DHCP will offer addresses, or not. Used only
+  when creating new network. Default is true.
+* `:libvirt__adapter` - Number specifiyng sequence number of interface.
