 ### Steps to reproduce
 
-### Versions

+configuration.
 
-In case you are not using jedi-vim from Git master, please test it there, too.
+You can use the following template (save it as `minimal.vimrc`, and run Vim
+with `vim -u minimal.vimrc`):
 
-### Output of the "JediDebugInfo" command (in a Python buffer)
+```
+set nocompatible
 
-### Output of the "messages" Vim command
+let script_dir = fnamemodify(expand('<sfile>'), ':h')
+let &runtimepath .= ','.script_dir.','.script_dir.'/after'
 
-### Output of "scriptnames" Vim command
+" Put your config changes here.
+" let g:jedi#show_call_signatures=1
+
+syntax on
+filetype plugin indent on
+```
