+### 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.

+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

 The first thing you need after that is an up-to-date version of Jedi. You can

-in your jedi-vim repository.

+The completion is too slow!
+---------------------------
 
-Completion of complex libraries (like Numpy) should only be slow the first time

+1. Completion of complex libraries (like Numpy) should only be slow the first
+   time you complete them. After that the results should be cached and very fast.
 
-If it's still slow, in case you've installed the python-mode VIM plugin, disable
-it. It seems to conflict with jedi-vim. See issue `#163
-<https://github.com/davidhalter/jedi-vim/issues/163>`__.
+2. If it is still slow after the initial completion and you have installed the
+   python-mode Vim plugin, try disabling its rope mode:
 
+   .. code-block:: vim
+
+       let g:pymode_rope = 0
+
+   See issue `#163 <https://github.com/davidhalter/jedi-vim/issues/163>`__.
+
+3. You can also use `deoplete-jedi <https://github.com/zchee/deoplete-jedi>`__
+   for completions, which uses Jedi, but does completions asynchronously
+   (requires Neovim).
+   It makes sense to use both jedi-vim and deoplete-jedi, but you should disable
