+## Azure Blob Storage (azure\_blob\_storage)
+
+Adapter for Microsoft Azure Blob Storage service. To use this adapter you need to install the
+[Azure SDK for php](http://www.windowsazure.com/en-us/develop/php/common-tasks/download-php-sdk/) into your project.
+
+Further more you need a valid *connection string* and you must define a Blob Proxy factory service with it. You can use
+the default `\Gaufrette\Adapter\AzureBlobStorage\BlobProxyFactory` this way:
+
+``` yaml
+# app/config/config.yml
+services:
+    azure_blob_proxy_factory:
+        class: Gaufrette\Adapter\AzureBlobStorage\BlobProxyFactory
+        arguments: [%azure_blob_storage_connection_string%]
+```
+
+You must set the parameter `azure_blob_storage_connection_string` to contain your windows azure blob storage connection
+string. You can retrieve your connection string in your [Windows Azure management console](https://manage.windowsazure.com).
+
+### Parameters
+
+ * `blob_proxy_factory_id` Reference to the blob proxy factory service
+ * `container_name` The name of the container
+ * `create_container` Boolean value that indicates whether to create the container if it does not exists (*optional*: default *false*)
+ * `detect_content_type` Boolean value that indicates whether to auto determinate and set the content type on new blobs (*optional*: default *true*)
+
+### Example
+
+``` yaml
+# app/config/config.yml
+knp_gaufrette:
+    adapters:
+        foo:
+            azure_blob_storage:
+                blob_proxy_factory_id: azure_blob_proxy_factory
+                container_name: my_container
+                create_container: true
+```
+
 ## GridFS (gridfs)
 
 Adapter that allows you to use a MongoDB GridFS for storing files.
