+Install
+=======
+
+NetworkDisk requires Python3.6.
+
+Below we assume you have the default Python environment already configured on
+your computer and you intend to install ``networkx`` inside of it.  If you want
+to create and work with Python virtual environments, please follow instructions
+on `venv <https://docs.python.org/3/library/venv.html>`_ and `virtual
+environments <http://docs.python-guide.org/en/latest/dev/virtualenvs/>`_.
+
+First, make sure you have the latest version of ``pip`` (the Python package manager)
+installed. If you do not, refer to the `Pip documentation
+<https://pip.pypa.io/en/stable/installing/>`_ and install ``pip`` first.
+
+Installing with dependencies
+----------------------------
+
+To install ``QueryBuilder`` with dependencies from source, run the following command from the package root directory::
+
+    $ python3 -m pip install .
+
+To install optional dependencies to run tests or generate documentation, run the following commands from the package root directory::
