+## Pagination
+
+List methods in the Orb API are paginated.
+
+This library provides auto-paginating iterators with each list response, so you do not have to request successive pages manually:
+
+```ruby
+page = orb.coupons.list
+
+# Fetch single item from page.
+coupon = page.data[0]
+puts(coupon.id)
+
+# Automatically fetches more pages as needed.

+## Sorbet Support
+
+This library is written with [Sorbet type definitions](https://sorbet.org/docs/rbi). However, there is no runtime dependency on the `sorbet-runtime`.
+
+What this means is that while you can use Sorbet to type check your code statically, and benefit from the [Sorbet Language Server](https://sorbet.org/docs/lsp) in your editor, there is no runtime type checking and execution overhead from Sorbet itself.
+
+Due to limitations with the Sorbet type system, where a method otherwise can take an instance of `Orb::BaseModel` class, you will need to use the `**` splat operator to pass the arguments:
+
+```ruby
+model = CustomerCreateParams.new(email: "example-customer@withorb.com", name: "My Customer")
+
+orb.customers.create(**model)
+```
+
 ## Versioning
 
-This package follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions. As the
-library is in initial development and has a major version of `0`, APIs may change
-at any time.
