 # Open Food Network
 
-The Open Food Network is an online marketplace for local food. It enables a network of independent online food stores that connects farmers and food hubs (including co-ops, online farmers markets, independent food businesses, etc) with individuals and local businesses. It gives farmers and food hubs an easier and fairer way to distribute their food.

It gives farmers and food hubs an easier and fairer way to distribute their food.
 
 Supported by the Open Food Foundation and a network of global affiliates, we are proudly open source and not-for-profit - we're trying to seriously disrupt the concentration of power in global agri-food systems, and we need as many smart people working together on this as possible.
 
 We're part of global movement - get involved!
