 ### Autogenerated Content Transformers

+For autogenerated pages (REST, GraphQL, webhooks, landing pages, audit logs, etc), the Article API uses specialized transformers to convert the rendered content into markdown format. These transformers are located in `src/article-api/transformers/` and use an extensible architecture:
+
+#### Current Transformers
+
+- **REST Transformer** (`rest-transformer.ts`) - Converts REST API operations into markdown, including endpoints, parameters, status codes, and code examples
+- **GraphQL Transformer** (`graphql-transformer.ts`) - Converts GraphQL schema documentation into markdown, including queries, mutations, objects, interfaces, enums, unions, input objects, scalars, changelog, and breaking changes
 
 To add a new transformer for other autogenerated content types:
 1. Create a new transformer file implementing the `PageTransformer` interface

+## About breaking changes
+
+Breaking changes are any changes that might require action from our integrators. We divide these changes into two categories:
+
+* **Breaking:** Changes that will break existing queries to the GraphQL API. For example, removing a field would be a breaking change.
+* **Dangerous:** Changes that won't break existing queries but could affect the runtime behavior of clients. Adding an enum value is an example of a dangerous change.
+
+We'll announce upcoming breaking changes at least three months before making changes to the GraphQL schema, to give integrators time to make the necessary adjustments.

+---
+
+## About input objects
+
+Input objects are used when you need to pass a structured set of values as an argument to a field. They are similar to regular objects, but they are specifically designed to be used as input arguments.
