+Below are the build instructions for Arch Linux over the Raspberry Pi
+
+These instructions assume that your Arch Linux installation is up and running on
+the Raspberry Pi with full network access. If not, please visit the following
+Web sites for further instructions. As always, Google will also be your friend.
+https://www.raspberrypi.org/documentation/
+https://wiki.archlinux.org/index.php/Raspberry_Pi
+
+
+* Update your Arch Linux installation:
+
+    sudo pacman -Syu
+
+* Install required packages:
+
+    pacman -S git gcc cmake bison flex make openmpi --needed base-devel 
+
+* Create the foam-extend installation directory:
+
+These instructions assume that you install in the default location, which is
+~/foam/ . Create this folder with:
+
+    mkdir ~/foam
+
+* Obtain and unpack source code (if you read this, you probably already have):
+
+The recommended way is to get the source code through git source code
+management system. This way, you can get updates and bugfixes easily by running
+"git pull". To install into the default location run:
+
+    cd ~/foam
+    git clone git://git.code.sf.net/p/foam-extend/foam-extend-3.2
+
+* For Arch Linux, you need to customize your file etc/prefs.sh in order to enable
+  the usage of system-provided packages, and to enable the compilation of other.
+
+  Here is a list of commands that will do just that. You can copy/paste
+  the following block of commands in a control terminal in order to make
+  the necessary adjustments. You will need to be located at the root of your
+  foam-extend-3.2 installation for those commands to work.
