+### Issue
+
+<!--
+Please describe the issue here.
+
+If you are not using jedi-vim from Git (but e.g. from a distribution's package,
+please try it with jedi-vim's Git master, too).
+-->
+
+### Steps to reproduce
+
+<!--
+Include if relevant.
+
+Please provide steps to reproduce it here, preferably based on a minimal Vim
+configuration.
+
+You can use the following template (save it as `minimal.vimrc` in the directory
+where jedi-vim is installed, `cd` into that directory, and run Vim with
+`vim -u minimal.vimrc`):
+
+```
+set nocompatible
+
+let script_dir = fnamemodify(expand('<sfile>'), ':h')
+let &runtimepath .= ','.script_dir.','.script_dir.'/after'
+
+" Put your config changes here.
+" let g:jedi#show_call_signatures=1
+
+syntax on
+filetype plugin indent on
+```
+
+Please provide the `minimal.vimrc` you have used here, too.
+-->
+
+### Output of “:verbose JediDebugInfo”
+
+<!--
+Please execute `:redir @+> | silent verb JediDebugInfo | redir END` in a
+Python buffer to copy debug information into your clipboard.
+Then paste it here.

 Installation
 ============
 
+Requirements
+------------
+You need a VIM version that was compiled with Python 2.6 or later
+(``+python`` or ``+python3``), which is typical for most distributions on
+Linux.  You can check this from within VIM using
+``:python3 import sys; print(sys.version)`` (use ``:python`` for Python 2).
+
+Manual installation
+-------------------
+
 You might want to use `pathogen <https://github.com/tpope/vim-pathogen>`_ or
-`vundle <https://github.com/gmarik/vundle>`_ to install jedi in VIM. Also you
-need a VIM version that was compiled with ``+python``, which is typical for most
-distributions on Linux.
+`Vundle <https://github.com/gmarik/vundle>`_ to install jedi-vim.
 
 The first thing you need after that is an up-to-date version of Jedi. You can
-either get it via ``pip install jedi`` or with ``git submodule update --init``
-in your jedi-vim repository.
+either install it via ``pip install jedi`` or with
+``git submodule update --init`` in your jedi-vim repository.
 
-On Arch Linux, you can also install jedi-vim from AUR: `vim-jedi
-<https://aur.archlinux.org/packages/vim-jedi/>`__.
+Example installation command using Pathogen:
+
+.. code-block:: sh
+
+    git clone --recursive https://github.com/davidhalter/jedi-vim.git ~/.vim/bundle/jedi-vim
+
+Example installation using Vundle:
+
+Add the following line in your `~/.vimrc`
+    
+.. code-block:: vim
+
+    Plugin 'davidhalter/jedi-vim'
+
+
+Installation with your distribution
+-----------------------------------
+
+On Arch Linux, you can also install jedi-vim from official repositories as
+`vim-jedi <https://www.archlinux.org/packages/community/any/vim-jedi/>`__.
+It is also available on
+`Debian (≥8) <https://packages.debian.org/vim-python-jedi>`__ and
+`Ubuntu (≥14.04) <http://packages.ubuntu.com/vim-python-jedi>`__ as
+vim-python-jedi.
+On Fedora Linux, it is available as
+`vim-jedi <https://apps.fedoraproject.org/packages/vim-jedi>`__.
+
+Please note that this version might be quite old compared to using jedi-vim
+from Git.
+
+Caveats
+-------
 
 Note that the `python-mode <https://github.com/klen/python-mode>`_ VIM plugin seems
 to conflict with jedi-vim, therefore you should disable it before enabling
 jedi-vim.
 
-To enjoy the full features of Jedi-Vim, you should have VIM >= 7.3. For older 
-version of VIM, the parameter recommendation list maybe not appeared when you type
-open bracket after the function name.
