 ## How to use
 
-   
+Once configured, your project is ready to handle HTTP `GET` request on `/doc/{?filename}` endpoint.
+
+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],
+       ...
+   ];
+   ```
+   
+ - Add the following in your routing configuration :
+   ```yaml
+   # config/routes.yaml
+   json-rpc-endpoint:
+     resource: '@JsonRpcHttpServerBundle/Resources/config/routing/endpoint.xml'
+   
+   json-rpc-endpoint-doc:
+     resource: '@JsonRpcHttpServerDocBundle/Resources/config/routing/endpoint.xml'
+   ```
+   
+ - Add the following in your configuration :
+   ```yaml
+   # config/config.yaml
+   framework:
+     secret: '%env(APP_SECRET)%'
+
+   json_rpc_http_server: ~
+   
+   json_rpc_http_server_doc: ~
+   # Or the following in case you want to customize endpoint path
+   #json_rpc_http_server_doc:
+   #  endpoint: '/my-custom-doc-endpoint' # Default to '/doc'
+   ```
+   
+ - Register JSON-RPC methods as described on [yoanm/symfony-jsonrpc-http-server](https://github.com/yoanm/symfony-jsonrpc-http-server) documentation.
+ 
+ - Query your project at `/doc` endpoint and you will have a `json` documentation of your server.
