 You can install |jedi| directly from official AUR packages:
 
-- `python-jedi <https://aur.archlinux.org/packages/python-jedi/>`__
-- `python2-jedi <https://aur.archlinux.org/packages/python2-jedi/>`__
+- `python-jedi <https://aur.archlinux.org/packages/python-jedi/>`__ (Python 3)
+- `python2-jedi <https://aur.archlinux.org/packages/python2-jedi/>`__ (Python 2)
+
+The specified Python version just refers to the *runtime environment* for
+|jedi|. Use the Python 2 version if you're running vim (or whatever editor oyu
+use) under Python 2. Otherwise, use the Python 3 version. But whatever version
+you choose, both are able to complete both Python 2 and 3 *code*.
 
 (There is also a packaged version of the vim plugin available: `vim-jedi at AUR
 <https://aur.archlinux.org/packages/vim-jedi/>`__.)
