-This version of tinc relies on the GNU Multi-Precision Library
-(gmp). This library is available from your nearest GNU mirror. Please
-install this first even before trying to run configure. If you don't
-do this, configure will (hopefully) mention it to you.
-
-This version of tinc supports multiple virtual networks at once. To
-use this feature, you may supply a netname via the -n or --net
-options. The standard locations for the config files will then be
-/etc/tinc/<net>/.
-
-In this version, MAC addresses are stripped off before encoding and
-sending a packet. When the packet reaches its destination, the MAC
-addresses are rebuilt again. They then have the form
-FE:FD:aa:bb:cc:dd. aa, bb, cc and dd are taken from the destination
-and source IP address.
-
-tincd regenerates its encryption key pairs. It does this on the first
-activity after the keys have expired. This period is adjustable in the
-configuration file, and the default time is 3600 seconds (one
-hour). If you send a USR2 signal to the daemon, it'll regenerate
-immediately.

+Security statement
+------------------
+
+In august 2000, we discovered the existence of a security hole in all versions
+of tinc up to and including 1.0pre2. This had to do with the way we exchanged
+keys. Since then, we have been working on a new authentication scheme to make
+tinc as secure as possible. The current version uses the OpenSSL library and
+does authentication in much the same way as the SSH protocol does.
+
+Cryptography is a hard thing to get right. We cannot make any guarantees. Time,
+review and feedback are the only things that can prove the security of any
+cryptographic product. If you wish to review tinc or give us feedback, you are
+stronly encouraged to do so.
+
+Requirements
+------------
+
+Since 1.0pre3, we use OpenSSL for all cryptographic functions. So you need to
+install this library first; grab it from http://www.openssl.org/. We recommend
+version 0.9.5 or better. If this library is not installed on you system,
+configure will fail. The manual in doc/tinc.texi contains more detailed
+information on how to install this library.
+
+
+Features
+--------
+
+This version of tinc supports multiple virtual networks at once. To use this
+feature, you may supply a netname via the -n or --net options. The standard
+locations for the config files will then be /etc/tinc/<net>/. Because of this
+feature, tinc will send packets directly to their destinations, instead of to
+the uplink. If this behaviour is undesirable (for instance because of firewalls
+or other restrictions), please use an older version of tinc (I would recommend
+tinc-0.2.19).
+
+In order to force the kernel to accept received packets, the destination MAC
+address will be set to FE:FD:00:00:00:00 upon reception. The MAC address of the
+ethertap or tun/tap interface must also be set to this address. See the manual
+for more detailed information.
+
+tincd regenerates its encryption key pairs. It does this on the first activity
+after the keys have expired. This period is adjustable in the configuration
+file, and the default time is 3600 seconds (one hour).
+
+This version supports multiple subnets at once. They are also sorted on subnet
+mask size. This means that it is possible to have overlapping subnets on the
+VPN, as long as their subnet mask sizes differ.
