This is a very tiny Flask application. Because of this, it is highly recommended that you use a python virtualenvironment to get set up. For a how-to on getting set up, please consult this howto.
Once you have created your virtual environment, follow these instructions to bootstrap your environment:
https://github.com/<your_fork>/tinysphinx
cd tinysphinx
pip install -r requirements.txt
python tinysphinx.py
You should now have your very own tinysphinx app running at 127.0.0.1:9000.
