 Yggdrasil Network is a peer-to-peer IPv6 network with link-local peer discovery, automatic end-to-end encryption, distributed IP address allocation, and DHT-based routing information exchange.
 
-## How to install on a Raspberry Pi
+## Supported devices
 
-Flash the downloaded firmware to the SD card (i.e. /dev/mmcblk0 or /dev/sdb):
+This firmware can be installed on any device supported by OpenWrt with at least 16MB flash size and 64MB RAM.
 
-```
-gunzip -c openwrt-21.02.1-bcm27xx-bcm2711-rpi-4-ext4-factory.img.gz | sudo dd of=/dev/mmcblk0 bs=2M status=progress
-```
-
-## Usage
+Support for 802.11s wireless peer to peer connections depends on a wireless driver. Most up to date open source drivers work (ath9k, mt76).
 
-Connect your device to a home network and find an IP address of a device called `HyperModem` (it connects via DHCP).
+## Installation and usage
 
-Login to the web interface (i.e. http://192.168.1.100) and set the root password.
-
-Configure physical links, install extra OpenWrt packages, do whatever you want with your own *Popura HyperModem ™* mesh node.
+Search the OpenWrt website for detailed instructions for your device.
