+# Yoga Persisted Documents Example
+
+Example for showing how to use GraphQL Code Generator for only allowing the execution of persisted operations.
+
+[Learn more about Yoga Persisted Operations](https://the-guild.dev/graphql/yoga-server/docs/features/persisted-operations)
+
+## Usage
+
+Run `yarn codegen --watch` for starting GraphQL Code Generator in watch mode.
+
+Run `yarn test` for running a tests located within `yoga.spec.ts`.
