Before setting up the recommendations module, you need to import a product feed. After that, fill in:

• Your field of activity - this is necessary for more accurate work of algorithms and service improvement
• Out-of-stock products - specify how your product feed displays out-of-stock products (they are absent or present with a certain value of some parameter).
• Product feed with authorization - if you want to receive product recommendations in a secure way, specify a login and password that will be used on the side of your site to access the recommendations.
• Setting up attribution (time attribution) - here you can specify the time period within which the order of the recommended product will be counted as a purchase from recommendations
