Flask is a popular Python-based micro framework. Here is how to install it on WebFaction.

This is based on the Flask instructions and the WebFaction instructions.

1. Log into your WebFaction control panel
2. Domains/Websites -> Applications -> Add new application

   2. Add an application -> Reuse an existing application
