Open up settings.py and modify all the keys you need to change.

It's especially important to modify the DATABASE_URI as it's currently set to create a database in /tmp (You don't want to lose all your data on reboot!)

In mturk.py, you'll want to change the value for "host" at line 16 - by default it's set to connect to the Mechanical Turk sandbox to make sure everything else is good before incurring costs.

Start the tool with

python main.py
