+distributions on Linux.  The Python version compiled into VIM must be 2.6 or later
+(you can check this from within VIM using ``:python import sys; print sys.version`` )
 
 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.
 
-On Arch Linux, you can also install jedi-vim from AUR: `vim-jedi

+
+
+On Arch Linux, you can also install jedi-vim from official repositories as `vim-jedi

 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.

+It is best if you have VIM >= 7.3, compiled with the `+conceal` option. With
+older versions, you will probably not see the parameter recommendation list
+for functions after typing the open bracket. Some platforms (including OS X
+releases) do not ship a VIM with `+conceal`. You can check if your VIM has the
+feature with >
+
+    :ver
+
+and look for "`+conceal`" (as opposed to "`-conceal`") or >
+
+    :echo has('conceal')
+
+which will report 0 (not included) or 1 (included). If your VIM lacks this
+feature and you would like function parameter completion, you will need to
+build your own VIM, or use a package for your operating system that has this
+feature (such as MacVim on OS X, which also contains a console binary).
