-Preliminary support for routing IPv6 packets has been added. Just add Subnet
-lines with IPv6 addresses (without using :: abbreviations) and use ifconfig to
-give the virtual network interface corresponding IPv6 addresses.
-Autoconfiguration will not work in router mode.
+Support for routing IPv6 packets has been added. Just add Subnet lines with
+IPv6 addresses (without using :: abbreviations) and use ifconfig or ip (from
+the iproute package) to give the virtual network interface corresponding IPv6
+addresses. tinc does not provide autoconfiguration for IPv6 hosts, if you need
+it use radvd or zebra. Tunneling IPv6 packets only works on Linux, FreeBSD,
+Windows and possibly OpenBSD.
+
+It is also possible to make tunnels to other tinc daemons over IPv6 networks,
+if the operating system supports IPv6. tinc will automatically use both IPv6
+and IPv4 when available, but this can be changed by adding the option
+"AddressFamily = ipv4" or "AddressFamily = ipv6" to the tinc.conf file.
+
+Normally, when started tinc will detach and run in the background. In a native
+Windows environment this means tinc will intall itself as a service, which will
+restart after reboots. To prevent tinc from detaching or running as a service,
+use the -D option.
