 # GraphQL Backend
 
-## Getting Started
-
-This is the GraphQL Backend plugin.
-
-It is responsible for merging different `graphql-plugins` together to provide the end schema.
-
-To run it within the backend do:
-
-1. Register the router in `packages/backend/src/index.ts`:
-
-```ts
-const graphqlEnv = useHotMemoize(module, () => createEnv('graphql'));
-
-const service = createServiceBuilder(module)
-  .loadConfig(configReader)
-  /** several different routers */
-  .addRouter('/graphql', await graphql(graphqlEnv));
-```
-
-2. Start the backend
-
-```bash
-yarn workspace example-backend start
-```
-
-This will launch the full example backend.
+This package has been deprecated, consider using [@frontside/backstage-plugin-graphql-backend](https://www.npmjs.com/package/@frontside/backstage-plugin-graphql-backend) instead.
