+## CullaX
+CullaX will generate a dark Plasma theme based on your current wallpaper. It uses [colorgram.py](https://github.com/obskyr/colorgram.py)
+### Installation
+Firstly, install colorgram.py.  
+
+```
+sudo pip install colorgram.py
+```
+
+To install, just run ```./install.sh``` which will install the Plasma theme, a menu entry and the CullaX script. The menu entry should appear under the Settings submenu.
+
+
+ *Note: you need to set your own wallpaper before using CullaX.*
+
+
+If there's any interest, I'll add a light theme, a window decoration and maybe a settings panel.
