The tutorial referenced above explains how to setup a virtual environment with all the required modules. As a convenience, the `setup.py` script will create this virtual environment for you.

Note that to be able to run this script you have to have the following packages installed: The tutorial referenced above explains how to setup a virtual environment with all the required modules.
- Python 2.7
- Python development package (`python-dev` for most Linux distributions)
- git
The sqlite database must also be created before the application can run, and the `db_create.py` script takes care of that. See the [Database tutorial](http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-iv-database) for the details.
