Zones Table Rate Shipping Module

[devyani]

Hi,
I have installed this module. ( ie I have copied the files in the appropriate folders).
What is the next step?
When I click on admin->modules->shipping and select zone table rate, nothing seems to have changed.


So far I have done the following:
Thru localisation ->zonedefinitions I have added four sub zones under zone "India"


Now I want to assign different shipping rates for each of these zones, based on weight; as given by my courier service.
How do I do it ?
As of now, I have flat rate and store pickup enabled.

Thanks
