+The translations object in the Configuration resource allows defining custom text for the Aidbox Form Builder and Renderer.
+It uses a structured, hierarchical format where each key corresponds to a feature or component, and the leaf nodes specify locale-based translations.
 This structure supports multiple languages and regional variations by enabling you to specify locale codes such as en for English, fr for French, or more granular options like en-US for American English and fr-CA for Canadian French.
 
-The example provided below represents a comprehensive translations object for English, covering all possible keys. You can extend this object by adding translations for additional languages.

+description: This article explains how to configure Aidbox Forms to store attachments in S3-Compatible storages
+---
+
+# Overview
+
+Aidbox Forms provides an ability to store files from attachment items in cloud storages like S3.
+
+## 1. Setup storage account
+
+Aidbox supports Amazon S3, Google Cloud Storage, Azure Container.
+Here is the guide on [how to setup this integration](/storage-1/s3-compatible-storages).
+
+## 2. Update SDCConfig
+
+After you setup the integration put the reference to storage credential resource into the SDCConfig resource and set the bucket.
+
+```json
+{"resourceType": "SDCConfig",
+ "default": true,
+ "storage": {
+   "account": {
+     "id": "test-account",
+     "resourceType": "AwsAccount"
+   },
+   "bucket": "sdc-files"
+ }
+}
+```
+
+Now all files from attachment items will be stored in cloud storage.
