This module is used to offer shipping from a minimum amount on a specific shipping zone.
This module must be into your modules/ directory (thelia/local/modules/).
You can download the .zip file of this module or create a git submodule into your project like this :
cd /path-to-thelia
git submodule add https://github.com/thelia-modules/FreeShipping.git local/modules/FreeShipping
Next, go to your Thelia admin panel for module activation.
You can manage your free shipping rules on the configuration view of the module with the "configure" button on the modules list.
After defining a rule, commands that respect it will have their shipping costs equal to 0 (the shipping costs will be calculated automatically).
