 There are [other deployment strategies](https://github.com/magento/magento-composer-installer/blob/master/doc/Deploy.md) that could be used; however, we don't guarantee that any of them will work.
 
+## Usage `extra/chmod`
+
+The following example shows how you can set specific permissions for files.
+
+Example:
+
+```json
+{
+    "name": "magento/module-sample",
+    "description": "N/A",
+    "require": {
+        ...
+    },
+    "type": "magento2-module",
+    "extra": {
+         "chmod": [
+            {
+                "mask": "0755",
+                "path": "bin/magento"
+            },
+            {
+                "mask": "0644",

+            }
+        ]
+    }
+}

+
+`mask` is a bit mask for chmod command
+
+`path` is a path to file relative to the Magento root folder

 - The extra->magento-root-dir option is no longer supported. It displays only to preseve backward compatibility.
