+## Upgrade
+To upgrade the installation, you simply need to upload files from the new package overwriting existing files. Directory structure is organized to have each new version installed to a different directory. Only a few files will be actually overwritten (/index.php and /snappymail/v/VERSION).
+
+All the additional reconfiguration will be done by the product on next run.
