+IPython autojump magic
 
-# This tool provides "j" for ipython
-# To use it, copy it in your ~/.ipython directory
-# and add the following line to ipy_user_conf.py:
-# import autojump_ipython
+Written by keith hughitt <keith.hughitt@gmail.com>, based on an earlier
+version by Mario Pastorelli <pastorelli.mario@gmail.com>.
 
+To install, `create a new IPython user profile <http://ipython.org/ipython-doc/stable/config/ipython.html#configuring-ipython>`_
+if you have not already done so by running:
+
+    ipython profile create
+    
+And copy this file into the "startup" folder of your new profile (e.g. 
+"$HOME/.config/ipython/profile_default/startup/").
+
+@TODO: extend %cd to call "autojump -a"
