     If your IDE creates configuration files inside project's directory,
-    you can use ``.git/info/exclude`` file to exclude them. Here is an example

-    Symfony 2 folder:
-
-    .. code-block:: text
-
-        /ide-cfg
-        /ide.cfg

+    ``.git/info/exclude`` file (per project) to ignore them. See
+    [Github's documentation](https://help.github.com/articles/ignoring-files)
