​
Default configuration

By default Spree is mounted at the root of your domain, this code will be inserted into config/routes.rb: 
mount Spree::Core::Engine, at: '/'
This means that Spree will be available at the root of your domain, for example http://localhost:3000.

​
Customizing the mount point

You can customize this simply by changing the :at specification in config/routes.rb to be something else. For example, if you would like Spree to be mounted at /shop, you can write this: 
mount Spree::Core::Engine, at: `/shop`
The different parts of Spree (API, Admin) will be mounted there as well, eg. http://localhost:3000/shop/products.
