+This module is tested for Python 2 and 3 compatibility, and works on both
+Windows and Linux. Testing for Mac is on the way, but in theory it should work.
+Python 2 and 3 compatibility is achieved with a single code base with the help
+of the Python module [future](http://python-future.org/index.html).
 
 Switching to Python 3 is in general a very good idea especially since Python 3.5
 was released. Some even dare to say it
 [is like eating your vegetables](http://nothingbutsnark.svbtle.com/porting-to-python-3-is-like-eating-your-vegetables).
+So if you are still on Python 2, we would recommend you to give Python 3 a try!
