+
+## Configuration
+
+By default, the Doctrine DBAL connection used is `default`. You can configure the default connection.
+Add this configuration into your Symfony configuration:
+
+```yaml
+code_rhapsodie_dataflow:
+  dbal_default_connection: test #Name of the default connection used by Dataflow bundle
+```
+
+By default, the `logger` service will be used to log all exceptions and custom messages.
+If you want to use another logger, like a specific Monolog handler, Add this configuration:
+
+```yaml
+code_rhapsodie_dataflow:
+  default_logger: monolog.logger.custom #Service ID of the logger you want Dataflow to use
+```
+
+### Messenger mode
+
+Dataflow can delegate the execution of its jobs to the Symfony messenger component, if available.
+This allows jobs to be executed concurrently by workers instead of sequentially.
+
+To enable messenger mode:
+```yaml
+code_rhapsodie_dataflow:
+  messenger_mode:
+    enabled: true
+    # bus: 'messenger.default_bus' #Service ID of the bus you want Dataflow to use, if not the default one
+```
+
+You also need to route Dataflow messages to the proper transport:
+```yaml
+# config/packages/messenger.yaml
+framework:
+  messenger:
+    transports:
+      async: '%env(MESSENGER_TRANSPORT_DSN)%'
+
+    routing:
+      CodeRhapsodie\DataflowBundle\MessengerMode\JobMessage: async
+```

 With this configuration, the option `fileName` is required. For an advanced usage of the option resolver, read the [Symfony documentation](https://symfony.com/doc/current/components/options_resolver.html).
 
+For asynchronous management, `AbstractDataflowType` come with two default options :
+- loopInterval : default to 0. Update this interval if you wish customise the `tick` loop duration.
+- emitInterval : default to 0. Update this interval to have a control when reader must emit new data in the flow pipeline.
+
+### Logging
+
+All exceptions will be caught and written in the logger.
+If you want to add custom messages in the log, you can inject the logger in your readers / steps / writers.
+If your DataflowType class extends `AbstractDataflowType`, the logger is accessible as `$this->logger`.
+
+```php
+<?php

+use Symfony\Component\OptionsResolver\OptionsResolver;

+When using the `code-rhapsodie:dataflow:run-pending` command, this logger will also be used to save the log in the corresponding job in the database.

+#### CollectionWriter
+
+If you want to write multiple items from a single item read, you can use the generic `CollectionWriter`. This writer will iterate over any `iterable` it receives, and pass each item from that collection to your own writer that handles single items.
+
+```php
+$builder->addWriter(new CollectionWriter($mySingleItemWriter));
+```
+
+#### DelegatorWriter
+
+If you want to call different writers depending on what item is read, you can use the generic `DelegatorWriter`.
+
+As an example, let's suppose our items are arrays with the first entry being either `product` or `order`. We want to use a different writer based on that value.
+
+First, create your writers implementing `DelegateWriterInterface` (this interface extends `WriterInterface` so your writers can still be used without the `DelegatorWriter`).
+
+```php
+<?php
+namespace CodeRhapsodie\DataflowExemple\Writer;
+
+use CodeRhapsodie\DataFlowBundle\DataflowType\Writer\WriterInterface;
+
+class ProductWriter implements DelegateWriterInterface
+{
+    public function supports($item): bool
+    {
+        return 'product' === reset($item);
+    }
+
+    public function prepare()
+    {
+    }
+
+    public function write($item)
+    {
+        // Process your product
+    }
+
+    public function finish()
+    {
+    }
+}
+```
+
+```php
+<?php
+namespace CodeRhapsodie\DataflowExemple\Writer;
+
+use CodeRhapsodie\DataFlowBundle\DataflowType\Writer\WriterInterface;
+
+class OrderWriter implements DelegateWriterInterface
+{
+    public function supports($item): bool
+    {
+        return 'order' === reset($item);
+    }
+
+    public function prepare()
+    {
+    }
+
+    public function write($item)
+    {
+        // Process your order
+    }
+
+    public function finish()
+    {
+    }
+}
+```
+
+Then, configure your `DelegatorWriter` and add it to your dataflow type.
+
+```php
+    protected function buildDataflow(DataflowBuilder $builder, array $options): void
+    {
+        // Snip add reader and steps
+
+        $delegatorWriter = new DelegatorWriter();
+        $delegatorWriter->addDelegate(new ProductWriter());
+        $delegatorWriter->addDelegate(new OrderWriter());
+
+        $builder->addWriter($delegatorWriter);
+    }
+```
+
+During execution, the `DelegatorWriter` will simply pass each item received to its first delegate (in the order those were added) that supports it. If no delegate supports an item, an exception will be thrown.
