-Buildroot configuration for building a custom rootfs for KeyASIC WifiSD based cards.
+Buildroot configuration for building a custom rootfs for KeyASIC WifiSD based cards. This does not currently build a kernel, but that is [planned](https://github.com/dankrause/kcard-buildroot/issues/9). Check the [releases](https://github.com/dankrause/kcard-buildroot/releases) section for pre-built images that are ready to use immediately.
+
+To build your own image on Ubuntu derivatives:
+
+```bash
+# install buildroot dependencies (this list may be incomplete - contributions welcome)
+sudo apt-get install build-essential bison flex gettext libncurses5-dev texinfo autoconf automake libtool
+
+# download and extract buildroot 2013.08.1
+wget http://buildroot.uclibc.org/downloads/buildroot-2013.08.1.tar.bz2
+tar -xf buildroot-2013.08.1.tar.bz2
+
+# clone kcard-buildroot
+git clone https://github.com/dankrause/kcard-buildroot.git
+
+# create symlinks from buildroot to kcard-buildroot
+ln -s ../../kcard-buildroot/board/wifisd buildroot-2013.08.1/board/wifisd
+ln -s ../../kcard-buildroot/configs/wifisd_defconfig buildroot-2013.08.1/configs/wifisd_defconfig
+
+# start working with buildroot
+cd buildroot-2013.08.1
+
+# tell buildroot to start using the buildroot conf file that comes with kcard-buildroot
+make wifisd_defconfig
+
+# build a rootfs
+make
+```
+
+
+Once the build is complete, you should have an image (`output/images/initramfs3.gz`) ready for writing to your device. You still need to grab the kernel from [Dmitry Grinberg](http://dmitry.gr/index.php?r=05.Projects&proj=15.%20Transcend%20WiFiSD) if you haven't already.
