+swconfig binary packaged for Debian and derivatives
+---------------------------------------------------
+
+This repo contains the bare minimum needed to build
+the swconfig binary. All code is taken from OpenWRT
+project so their copyrights apply.
+
+BUILD:
+------
+
+Install build dependencies
+    apt-get install git build-essential fakeroot devscripts libnl-3-dev libnl-genl-3-dev
+
+As this utility talks to the switch driver in the kernel, kernel headers need to be in
+place and "switch.h" must be present otherwise the build will fail.
+
+If this file is missing, copy it from here and save to /usr/include/linux/ on the build machine:
+https://github.com/openwrt-mirror/openwrt/blob/master/target/linux/generic/files/include/uapi/linux/switch.h
+
+After all the above is done, clone the repo:
+    git clone https://github.com/jekader/swconfig.git
+    cd swconfig
+    bash build.sh
+    dpkg -i ../swconfig_15.04-1_armhf.deb
+
+USE:
+----
+
+Please read the upstream documentation on how to use this utility:
+http://wiki.openwrt.org/doc/techref/swconfig

+The code is owned by OpenWRT Project and taken from here:
+https://github.com/openwrt-mirror/openwrt/tree/master/package/network/config/swconfig/src
+
+Main difference from upstream: removed dependency of UCI and libnl-3 user instead of libnl-tiny
