-==== Example ====
+===== Installing openwrt on the router for the first time =====
+Go to the [[[https://firmware-selector.openwrt.org/|openwrt|firmware selector]]]. Select your device. Download the "factory" firmware and install it to your router as described on its openwrt wiki page. (e.g. [[[https://openwrt.org/toh/ubiquiti/edgerouter_x_er-x_ka|https://openwrt.org/toh/ubiquiti/edgerouter_x_er-x_ka]]])

+===== Generating the funkfeuer firmware image =====
+  - Go to the [[[https://firmware-selector.openwrt.org/|openwrt|firmware selector]]].
+  - Select your device.
+  - Click on "Customize installed packages and/or first boot script".
+  - Add the following packages to the list
+<file>curl mtr iperf3 tcpdump olsrd olsrd-mod-jsoninfo luci-app-olsr ethtool ipip kmod-ipip
+</file>
+  - Copy the following script and paste it to "Script to run on first boot (uci-defaults)" on the image builder website
+  - Replace xxx in the first line with your location's name
+  - (optional) change LAN_IP and LAN_NET
+The script contains some default values that make configuration easier.
