-Keep in mind that there are different method signatures depending on the action:
-
-- When operating on a collection (e.g. `.list`, `.create`) the method signature is
-  `method(params, opts)`.
-- When operating on resource (e.g. `.capture`, `.update`) the method signature is
-  `method(id, params, opts)`.
-- One exception is that `retrieve`, despite being an operation on a resource, has the signature
-  `retrieve(id, opts)`. In addition, it will accept a Hash for the `id` param but will extract the
-  `id` key out and use the others as options.

 ### StripeClient vs legacy pattern
 
 We introduced the `StripeClient` class in v13 of the Ruby SDK. The legacy pattern used prior to that version is still available to use but will be marked as deprecated soon. Review the [migration guide to use StripeClient](https://github.com/stripe/stripe-ruby/wiki/Migration-guide-for-v13) to move from the legacy pattern.

 Both indexer and accessors can be used to retrieve values of resource properties.
 
 ```ruby
-customer = Stripe::Customer.retrieve('cus_123456789')
+customer = client.v1.customers.retrieve('cus_123456789')
 puts customer['id']
 puts customer.id

 NOTE: If the resource property is not defined, the accessors will raise an exception, while the indexer will return `nil`.
 
 ```ruby
-customer = Stripe::Customer.retrieve('cus_123456789')
+customer = client.v1.customers.retrieve('cus_123456789')
