 # Dependencies
-* Python2.7 ( The extension has NOT been tested on Python3 )
+* Python 2/3  
+> For now the extension is Python2/3 compatible.  
+> However since now [Python2 has reached the EOL](https://www.python.org/doc/sunset-python-2/), all the feature will be tested on Python3 from now on.  
+> I'll try my best to keep this extension as a Python2/3 compatible project, however there's still a possibility that I might drop the support of Python2 in the future.
