+Permissions Plugin
+==================
+
+The ``permissions`` plugin allows you to set file permissions after they got written.
+
+To use the ``permissions`` plugin, enable it in your configuration (see
+:ref:`using-plugins`).
+
+Configuration
+-------------
+
+To configure the plugin, make an ``permissions:`` section in your configuration
+file. You need to use **octal modes** to configure permissions. 
+
+Here's an example::
+
+    permissions:
+        file: 644
