+## configuration ##
+
+The script needs a simple configuration. Modify ``config.example.php`` to fit your needs and save as ``config.php``
+
+```php
+<?php
+/**
+ * xkcd-Mailer configuration example
+ * Save me as config.php
+ */
+
+// Your timezone, PHP5 required.
+// See full list: http://www.php.net/manual/en/timezones.php

 ## caveats ##
 
 - Script doesn't check has the feed been updated, possibly causing old strip delivery
-- You have to modify script to change delivery address, config file could be the solution
