 Export GraphQL schemas to `.graphql` SDL files without generating any code. This is useful for creating portable, version-controllable schema artifacts that can then be used as input for code generation via `schemaFile` or `schemaDir`.
 
+Schema export uses a nested `schema` config object: `schema: { enabled, output, filename }`.
+
 ## When to Use
 
 - You want deterministic, portable builds that don't depend on a live database or endpoint at code generation time
