Select Settings from the left menu.
Under Organization, select Warehouse.
Select + New, enter the warehouse address, and save the details.

Expected result: The saved warehouse appears in the warehouse list with its address and a corresponding map pin. One warehouse can be designated as Primary, meaning orders use that warehouse first.
