# Loki Checkout

**The main Magento 2 core module of the LokiCheckout is called `LokiCheckout_Core`. It contains the barebones functionality of the checkout, based on another module called `Loki_Components` (plus some other modules). It also offers themes and grid layouts to modify the entire checkout quickly.**

The features of the core module are actually documented througout this site. So on this page, the focus is only to discuss the configuration settings of this module.

## Configuration settings

All configurations are found under **Store > Configuration > Loki > Loki Checkout**.

Some highlights of these settings:

- **General > Skin**: Switch between the multi-step checkout (**Default Skin (Multi Step)**) and the **One Step Skin**.
- **General > Address Grid Layout**: Choose how the address fields are arranged (by default **Default grid**).
- **Field settings > Enable Same As Billing Checkbox**: Show a checkbox *My billing and shipping address are the same*, so customers do not need to enter their address twice (enabled by default).
- **Field settings > Hide Region When Optional**: Hide the region field for countries where it is not required (enabled by default).
- **Field settings > Enable Vat ID Only For Companies**: Only show the VAT ID field once a company name has been entered (disabled by default).
- **Field settings > Capitalize Country In Address Preview**: Show the country in uppercase in address summaries (disabled by default).
- **Shipping settings > Select Default Shipping Method** and **Billing settings > Select Default Payment Method**: Automatically select the first available method.
- **Cart settings > Maximum items visible**: The number of products shown in the sidebar before the customer needs to expand the list (by default 3).
- **Newsletter settings > Subscribe by default**: Check the newsletter checkbox by default.
- **Debugging**: Options for developers only. Keep these disabled in production.

> Your developer can also fix most of these settings in the theme or a module, so that they always apply regardless of the Admin Panel value. In that case, changing the setting in the Admin Panel might have no effect. See [Overriding settings via the XML layout](/checkout/dev/basic-customizations/overriding-settings-via-layout).
