   The Kill Bill https://docs.killbill.io/latest/Kill-Bill-Glossary.html#catalog[catalog^] contains https://docs.killbill.io/latest/Kill-Bill-Glossary.html#products[products^] and https://docs.killbill.io/latest/Kill-Bill-Glossary.html#plans[plans^] definitions. This XML configuration file is really powerful and offers various options for handling https://docs.killbill.io/latest/Kill-Bill-Glossary.html#trial_phase[trials^], https://docs.killbill.io/latest/Kill-Bill-Glossary.html#addons[add-ons^], https://docs.killbill.io/latest/Kill-Bill-Glossary.html#upgrade[upgrades^] / https://docs.killbill.io/latest/Kill-Bill-Glossary.html#downgrade[downgrades^], and so forth. (For more information on the Kill Bill catalog, see the https://docs.killbill.io/latest/userguide_subscription.html#components-catalog[Catalog] section in the _Subscription Billing_ guide.)

  +For this tutorial, instead of starting with the XML catalog, you'll learn how to create a simple catalog using the API as well as adding one plan. You can find more information on the https://killbill.github.io/slate/#catalog-simple-plan[Simple Plan] endpoint in the API. 
   
   [NOTE]
   *Note:* The simple catalog supports a _subset_ of the regular XML catalog features and isn't intended to serve as a catalog in production. For more details on the simple catalog, see the https://killbill.github.io/slate/#catalog-simple-plan["Simple Plan"] section in the _API Reference_.
