-This repository holds IC-VPN keys and configuration.
+[![Build Status](https://travis-ci.org/freifunk/icvpn.svg?branch=master)](https://travis-ci.org/freifunk/icvpn)
+
+This repository contains the tinc hosts for ICVPN-Peers and several helper scripts.
+
+## Setup
+
+This network requires the use of the Tinc VPN Daemon. You should use at least version 1.0.24 or higher, also the
+current pre-release version 1.1pre11 seems to work just fine.
+
+### Clone the repository
+    # cd /etc/tinc/
+    # git clone https://github.com/freifunk/icvpn.git
+    # cd icvpn
+    # cp scripts/post-merge .git/hooks/
+
+### Create your tinc configuration
+
+Open your favorite editor and create the /etc/tinc/icvpn/tinc.conf.
+
+    Name=entenhausen1
+    Mode=switch
+More options can be found through
+
+    # man tinc.conf
+Afterwards create a keypair with tincd.
+
+    # tincd -n icvpn -K
+Hint: In version 1.1 this option was moved to the tinc binary and is called <code>generate-rsa-keys</code>.
+
+### Execute post-merge hook
+This step is necessary to populate your new configuration with infos about the metanodes.
+
+    # ./git/hooks/post-merge
+
+### Set up a cronjob to update the repository in regular intervals.
+
+    # crontab -e
+and insert for example
+
+    @daily cd /etc/tinc/icvpn/; git pull > /dev/null
+
+## What are meta nodes?
+
+Tinc has a ConnectTo configuration option that describes which peers on startup to connect *and* sync metadata to.
+
+Until now (2015/4) we had roughly 74 nodes, and every node connected to each other (full mesh). Tinc however 
+does not scale this way, because on each connect and disconnect all ConnectTo-lines are being notified of this
+and then notify their neighbours again. Many smaller nodes seemingly could not handle the amount of metadata generated 
+by this which resulted in TCP Zero Windows. They then disconnected, and reconnected, producing more metadata in
+the process, which was followed by even larger nodes queueing up metadata, which resulted in all nodes taking
+a massive cpu and memory hit. Memory usage of up to 1.5GB was spotted, accumulated in less than 12 hours.
+
+However for tinc to build its network graph it is sufficient, if all nodes only exchange metadata at a few nodes,
+which results in much less strain on the whole network. This is why we now use meta nodes, which are defined in
+the `./metanodes` file.
+
+Criteria for the selection of meta nodes are:
+
+1. autonomous system diversity
+2. community diversity
+3. ample resources (cpu, memory, traffic)
+
+When data needs to be transferd between two nodes, this will happen indepently of those meta nodes. Through the shared
+network graph a direct transfer is possible and will be tried: at first via UDP, then via TCP, then indirectly. While
+indirect routing is possible the meta nodes are not required to provide forwarding for those packets.
