+The project compiles on Linux, Mac OS X and Windows (MinGW/MSYS).
+
+it requires:
+- gcc >= 4.4
+- libpthread
+- libreadline
+- libusb
+- perl
+- an ARM cross-compiler to compile the firmware
+
+and optionally QT for the GUI
+
+
+To compile, just run "make".
+
+===========
+= Windows =
+===========
+The following is a complete list of packages required to setup the compile environment yourself. Alternatively you can download an archive of the full environment (see below).
+
+1 - Install QT SDK for Windows [1]
+
+In the following instructions, we'll assume you installed it to C:\QT
+
+2 - MSYS-1.0.11 [2]
+
+Just follow the installation procedure.
+When asked if you have MinGW installed and for its path, provide:
+C:/QT/mingw
+
+3 - readline-5.0-1-bin [5]
+
+From this archive, copy:
+bin/* to C:\QT\mingw\bin
+include/* to C:\QT\mingw\include
+lib/*.a to C:\QT\mingw\lib
+
+4 - libusb-win32-device-bin-0.1.12.2 [6]
+
+Be careful here, it is *NOT* working with the filter version!
+Likewise copy:
+include/usb.h to C:\QT\mingw\include
+lib/gcc/libusb.a to C:\QT\mingw\lib
+
+
+5 - Install DevkitPro [5]
+
+You'll need it to compile the firmware (ARM) side.
+You only need devkitARM, nothing more (no extra lib or anything else)
+Assuming you installed it to C:\devkitpro, make sure you set
+the DEVKITARM environment variable to /c/devkitPro/devkitARM :
+export DEVKITARM=/c/devkitPro/devkitARM
+
+6 - Install Strawberry Perl [6]
+
+7 - Setup a few variables
+
+In your shell from MSYS, make sure you set QTDIR to your QT installation:
+export QTDIR=/c/QT/qt
+And add its bin to your path as well:
+export PATH=$PATH:$QTDIR/bin
