+DynamoDbStore
+~~~~~~~~~~~~~
+
+The DynamoDbStore saves locks on a Amazon DynamoDB table. Install it by running:
+
+.. code-block:: terminal
+
+    $ composer require symfony/amazon-dynamodb-lock
+
+It requires a `DynamoDbClient`_ instance or a `Data Source Name (DSN)`_.
+This store does not support blocking, and expects a TTL to avoid stalled locks::
+
+    use Symfony\Component\Lock\Bridge\DynamoDb\Store\DynamoDbStore;
+
+    // a DynamoDbClient instance or DSN
+    $dynamoDbClientOrDSN = 'dynamodb://default/lock';
+    $store = new DynamoDbStore($dynamoDbClientOrDSN);
+
+The table where values are stored is created automatically on the first call to
+the :method:`Symfony\\Component\\Lock\\Bridge\\DynamoDb\\DynamoDbStore::save` method.
+You can also create this table explicitly by calling the
+:method:`Symfony\\Component\\Lock\\Bridge\\DynamoDb\\DynamoDbStore::createTable` method in
+your code.
