These notebooks document important parts of the toolkit used in the project. To open them make sure that ipython and its dependencies are installed. Then cd in the notebooks dir and hit ipython notebook.
The notebooks can be exported to html using the command
ipython nbconvert name-of-the-notebook.ipynb
It is possible that one has to install several dependencies for this command to work (for instance, pip install pygments and sudo apt-get install pandoc). Pygments might have to be installed globally as well (sudo apt-get install python-pygments).
