+
+
+Policy file
+-----------
+
+The policy file will list all possible actions on swift proxy.
+Action's format is: "<http verbe>_<swift entity>" (example: "get_container", "put_object", etc).
+
+    ...
+    "get_container": "rule:allowed_for_user",
+    "put_container": "rule:allowed_for_user",
+    "delete_container": "rule:allowed_for_user",
+    ...
+
+Policy file contains also two specific rules: "swift_owner" "reseller_request", they define
+when swift_owner and reseller_request headers are set to true, as those two value are part
+of the contract between the auth system and swift.
+
+    ...
+    "swift_owner": "rule:swift_reseller or rule:swift_operator",
+    "reseller_request": "rule:swift_reseller",
+    ...
+ 
+
+Example
+-------
+
+* To deny creation of new containers: set put_container to '!':
+
+        ...
+        "get_container": "rule:allowed_for_user",
+        "put_container": "!",
+        ...
+
+* To restrict creation of new container to users with role "admin":
+
+        ...
+        "get_container": "rule:allowed_for_user",
+        "put_container": "role:admin",
+        ...
+
+Limitations
+-----------
+
+* swiftpolicy does not support dynamic laoding of the policy file, and thus, swift proxy have
+to be restarted when policy file is updated.
