+
+* iPython contribution layer for Spacemacs (WIP)
+
+** Description 
+This layer adds support for the package =emacs-ipython-notebook=.
+
+Do not hesitate to check the original package README [[https://github.com/millejoh/emacs-ipython-notebook][here]]. Also the wiki has
+lots of informative stuff.
+
+** Features
+- Micro-State with "evilified" keybindings
+- Lazy-loading
+** TODO List
+- Maybe it'd be better if there was a state for this
+- Make more keybinding to =connect= to a python buffer.
+- Deleting visual regions don't work, find out why.
+- This is a WIP, feel free to collaborate.
+
+** Install
+*** Layer
+#+begin_src emacs-lisp
+  (setq-default dotspacemacs-configuration-layers '(ipython))
+#+end_src
+*** Dependencies
+Install iPython > 3
+#+begin_src sh
+  pip install ipython
+#+end_src
+*** What needs to be run
+Have an iPython notebook running
+#+begin_src sh
+  ipython notebook
+#+end_src
+
+** Key Bindings
+
+*** Open Notebook List
+This layer is lazy loaded so the micro-state will only work after you summon the
+command =ein:notebooklist-open= which is bound to =SPC a i n=
+*** Micro-state: =ipython-notebook= 
+Once you are in the ipython notebook you can activate the micro-state with
+=SPC a i n=

+** Screenshots
+*** Light
+[[img/light.png]]
+*** Dark
+[[img/dark.png]]
+
+** Bonus
+If you want to have a matplotlibrc that looks good with a dark background try
+using [[file:matplotlibrc][this]] =matplotlibrc=. Plot background is always transparent by default so
+it will look okay for most dark themes out there.
