+1 - Download
+
+A precompiled DevKitARM cross compiler tool chain package can be found at
+http://sourceforge.net/projects/devkitpro/files/devkitARM
+Select the one you need (32bit or 64bit) and unpack to a convinient place, eg
+$HOME/proxmark3/. It will create a devkitARM/ subdirectory.
+
+Of course, you will need a general compiling environment on your computer for
+the client and the libusb headers. In most distributions you will get all you
+need with the lsb-package (Linux Standard Base). In debian/ubuntu you simply
+call `aptitude install lsb libusb-dev`.
+
+For the graphical plot view, you might need the qtlibs (debian/ubuntu:
+libqt4-dev), too.
