+# Wifi control deamon packages feed
+
+## Description
+
+This is an OpenWrt package feed containing community 
+maintained wifictld packages.
+
+## Usage
+
+To use these packages, add the following line to the 
+feeds.conf
+in the OpenWrt buildroot:
+
+```
+src-git wifictld git@dev.sum7.eu:wifictld/wifictld.git
+```
+
+This feed should be included and enabled by default in the 
+OpenWrt buildroot. To install all its package definitions, 
+run:
+
+```
+./scripts/feeds update wifictld
+./scripts/feeds install -a -p wifictld
+```
+
+The wifictld packages should now appear in menuconfig.
