Start by configuring your basic store information under Configuration > General such as your store name, email, address, units of measure, etc. This information will be used by various functions of your Storefront such as calculating shipping cost based on your store address or sending email receipt to the customer.

The Storefront comes with many advanced features that are disabled by default such as Artificial Intelligence (AI), API, cross-sell, handling, packing, fraud score, address validation, etc. You may want to explore and enable some of these features once you have familiarized with the basic workings of the software.
