 ## Prerequisites installation
 
 Prerequisites are installed through `pip`. However, some of them are not "pip installable" and have
 to be installed manually.
 
-* All systems: [Python 3.3+][python] and [setuptools][setuptools]
-* Mac OS X: The last XCode to have the 10.7 SDK included. Python 3.4+.
-* Windows: Visual Studio 2010, [PyQt 5.0+][pyqt], [cx_Freeze][cxfreeze] and

+* All systems: [Python 3.4+][python]
+* Mac OS X: The last XCode to have the 10.7 SDK included.
 
 On Ubuntu (14.04+), the apt-get command to install all pre-requisites is:
 
-    $ apt-get install python3-dev python3-pyqt5 pyqt5-dev-tools
-
-On Arch, it's:
-
-    $ pacman -S python-pyqt5
