-**Note: This plugin is seeking a maintainer as the core team does not use this**
+## Python 2 vs Python 3

-###License
+Light Table v0.8.1 is using your system default Python, which on most Linux distributions in time of writing this means Python 2.
+If you want to check what is your system default Python, try ```ls -l /usr/bin/python``` you'll probably get something like this:
+
+    lrwxrwxrwx 1 root root 16 Lip  1 21:41 /usr/bin/python -> /usr/bin/python2
+
+If you want that Light Table for eval use some other version of Python, put in your ```user.behaviors``` following:
+
+    [:app :lt.plugins.python/python-exe "/usr/bin/pythonX"]
+
+where **X** is 3 or 3.5 or whatever Python version you have installed and you want to use with LightTable eval.
+
+##Terminology used
+
+For (maybe) unknown words like eval or REPL please check http://docs.lighttable.com/#what
+
+If by chance you see somewhere LT, it stands for Light Table, of course.
