About Remove shoppingcart from edx-platform

I saw the information:

Remove shoppingcart from edx-platform

I guess that the ENABLE_SHOPPING_CART should be removed.
If I want to set the course fee correctlly, how should I do ?
(version : Koa )

If you want to sell your courses, you should be using ecommerce, you can learn more here: 6. Adding E-Commerce to the Open edX Platform — Installing, Configuring, and Running the Open edX Platform documentation

The course “fees” and the shopping cart feature have not been used for quite some time. Instead you should create course seats in ecommerce 6.4.2. Create Course Seats — Installing, Configuring, and Running the Open edX Platform documentation

Hope this helps!
