Prerequisites

To "compile" documentation into html form you would need to install Sphinx documentation package, which should be relatively trivial.

If you're on macOS:

• Install from source: http://sphinx-doc.org/install.html

If you're on Ubuntu Linux 16.04:

sudo apt install python3-pip
sudo pip3 install -U pip setuptools
sudo pip3 install -U sphinx sphinxcontrib-bibtex sphinxcontrib-fulltoc

Compilation

Just type

make html

And a set of HTML pages will be build under _build/html

You can also type

make latexpdf

This way Sphinx will prepare .tex file and will try to build .pdf document.
