 All of the available OpenAPI decorators have an `Api` prefix to distinguish them from the core decorators. Below is a full list of the exported decorators along with a designation of the level at which the decorator may be applied.

 Both `Cat` and `Dog` must be defined as extra models using the `@ApiExtraModels()` decorator (at the class-level).
+
+#### Schema name
+
+As you may have noticed, the name of the generated schema is based on the name of the original model class (for example, the `CreateCatDto` model generates a `CreateCatDto` schema). If you'd like to change the schema name, you can use the `@ApiSchema()` decorator.
+
+Here’s an example:
+
+```typescript
+@ApiSchema({ name: 'CreateCatRequest' })
+class CreateCatDto {}
+```
+
+The model above will be translated into the `CreateCatRequest` schema.
