   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. 
  +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_.

  == Step 5. Set Up a Subscription for the Account
  
  You are now ready to create a https://docs.killbill.io/latest/Kill-Bill-Glossary.html#subscription[subscription^] for the customer.
  
  [NOTE]
  *Note:* Replace `1cb6c8b0-1df6-4dd5-9c7c-2a69bab365e8` below with the ID of your account. Also, `planName` must match the plan name in the catalog.

  To pay its https://docs.killbill.io/latest/Kill-Bill-Glossary.html#invoice[invoices^], an account must have at least one https://docs.killbill.io/latest/Kill-Bill-Glossary.html#payment_method[payment method^] saved. This section explains how to add a payment method to a customer account.
  
  For simplicity, we will create an offline payment method—checks—for the account we created in <<step1, Step 1>> using the https://killbill.github.io/slate/#account-add-a-payment-method[Add a Payment Method] endpoint.
