+The Storage library provides abstraction over different file storage providers.
+
+## Usage
+
+A module that needs file storage, it can be configured via `\Magento\Framework\Storage\StorageProvider` in `di.xml`:
+
+```xml
+<type name="Magento\Framework\Storage\StorageProvider">
+    <arguments>
+        <argument name="storage" xsi:type="array">
+            <item name="storage-name" xsi:type="string">default/location</item>
+        </argument>
+    </arguments>
+</type>
+```
+
+`default/location` is a default path in local filesystem, relative to Magento root.
+
+Now, in a PHP class that uses the declared storage, use the same `\Magento\Framework\Storage\StorageProvider` to get it:
+
+```php
+/**
+ * @var \Magento\Framework\Storage\StorageProvider
+ */
+private $storageProvider;
+
+public function doSomething()
+{
+    $storage = $this->storageProvider->get('storage-name')
+    $storage->put('path.txt', $content);
+}
+```
+
+## Configuring Storage
+
+A storage can be configured in `env.php`:
+
+```php
+'storage' => [
+    'storage-name' => [
+        'adapter' => 'aws_s3',
+        'options' => [
+            'client' => [
+                'credentials' => [
+                    'key'    => '<key>',
+                    'secret' => '<secret>'
+                ],
+                'region' => '<region>',
+                'version' => 'latest',
+            ],
+            'bucket' => '<bucket>',
+        ],
+    ],
+    'media' => [
+        // this is default configuration, so it doesn't need to be configured explicitly like so
+        'adapter' => 'local',
+        'options' => [
+            'root' => 'pub/media'
+        ]
+    ]
+]
+```
+
+Different providers have different `options` available for configuration.
+Under the hood, Magento Storage relies on [Flysystem](https://github.com/thephpleague/flysystem) library, so`options` might reflect options required by a corresponding storage adapter implemented for Flysystem.  
+
+## Storage Providers
+
+By default, Magento Storage provides support for the following storage providers:
+
+* Local filesystem (based on `\League\Flysystem\Adapter\Local`)
+   * Adapter name: `local`
+   * Options: 
+      ```php
+        [
+            'root' => 'path/relative/to/magento/root'
+        ]
+      ```
+* AWS S3 V3 (based on `\League\Flysystem\AwsS3v3\AwsS3Adapter`)
+   * Adapter name: `aws_s3`
+   * Options:
+       ```php
+          [
+              'client' => [
+                  'credentials' => [
+                      'key'    => '<key>',
+                      'secret' => '<secret>'
+                  ],
+                  'region' => '<region>',
+                  'version' => 'latest',
+              ],
+              'bucket' => '<bucket>',
+              'prefix' => '<prefix>',
+          ]
+        ```
+* Azure Blob storage (based on `\League\Flysystem\AzureBlobStorage\AzureBlobStorageAdapter`)
+   * Adapter name: `ms_azure`
+   * Options:
+        ```php
+          [
+              'connection_string' => '<connection-string>',
+              'container_name' => '<container-name>',
+              'prefix' => '<prefix>',
+          ]
+        ```
+
+Additional adapters can be added by:
+1. Creating an adapter factory implementing `\Magento\Framework\Storage\AdapterFactory\AdapterFactoryInterface`
+2. Registering the factory in `Magento\Framework\Storage\StorageProvider` via `di.xml`:     
+    ```xml
+        <type name="Magento\Framework\Storage\StorageProvider">
+            <arguments>
+                <argument name="storageAdapters" xsi:type="array">
+                    <item name="custom_adapter" xsi:type="string">My\Storage\AdapterFactory</item>
+                </argument>
+            </arguments>
+        </type>
+    ```
+
+The factory is registered as a "string" (name of the class).
+That's because in most cases only a few adapters will be really created for a single application, and we don't want to create unnecessary factory instances.
