+# openwrt-wan-failover
+
+This is a simple script/service that constantly pings your primary
+interface (WAN) and secondary interface (WWAN, though I suppose in
+practice it doesn't have to be a wireless WAN link).
+
+Install it with the `install.sh` script on your OpenWRT device, and
+either reboot, or start it immediately with `service wan-failover
+start`.
+
+There is currently no UI to configure it; use `uci` or manually edit the
+provided sample configuration file before installing.
+
+Before starting the service, you should set your primary interface's
+metric to 10, and the backup to 20.
