 Symfony bundle for easy JSON-RPC server OpenAPI 3.0.0 documentation
 
+Symfony bundle for [yoanm/jsonrpc-http-server-openapi-doc-sdk](https://github.com/yoanm/php-jsonrpc-http-server-openapi-doc-sdk)
+
 ## How to use
-   
+
+Once configured, your project is ready to handle HTTP `GET` request on `/doc/openapi.json` endpoint. Result will be a openapi compatible file.
+
+See below how to configure it.
+
+## Configuration
+
+[Behat demo app configuration folders](./features/demo_app) can be used as examples.
+
+ - Add the bundles in your config/bundles.php file:
+   ```php
+   // config/bundles.php
+   return [
+       ...
+       Symfony\Bundle\FrameworkBundle\FrameworkBundle::class => ['all' => true],
+       Yoanm\SymfonyJsonRpcHttpServer\JsonRpcHttpServerBundle::class => ['all' => true],
+       Yoanm\SymfonyJsonRpcHttpServerDoc\JsonRpcHttpServerDocBundle::class => ['all' => true],
+       Yoanm\SymfonyJsonRpcHttpServerOpenAPIDoc\JsonRpcHttpServerOpenAPIDocBundle::class => ['all' => true],
+       ...
+   ];
+   ```
+   
+ - Configure `yoanm/symfony-jsonrpc-http-server` as described on [yoanm/symfony-jsonrpc-http-server](https://github.com/yoanm/symfony-jsonrpc-http-server) documentation.
+ 
+ - Configure `yoanm/symfony-jsonrpc-http-server-doc` as described on [yoanm/symfony-jsonrpc-http-server-doc](https://github.com/yoanm/symfony-jsonrpc-http-server-doc) documentation.
+ 
+ - Query your project at `/doc/openapi.json` endpoint and you will have a OpenAPI json documentation file of your server.
+
+## Event
+
+You are able to enhance resulting documentation by listening on `json_rpc_http_server_openapi_doc.array_created` event.
+
+See below an example of listener service configuration:
+```yaml
+  method_doc_created.listener:
+    class: Full\Namespace\DocCreatedListener # <-- replace by your class name
+    tags:
+      - name: 'kernel.event_listener'
+        event: 'json_rpc_http_server_openapi_doc.array_created'
+        method: 'enhanceMethodDoc' # <-- replace by your method name
+``` 
+
+You will receive an event of type [`OpenAPIDocCreatedEvent`](./src/Event/OpenAPIDocCreatedEvent.php).
+
+You can take example on Behat [`DocCreatedListener`](./features/demo_app/src/Listener/DocCreatedListener.php)
