+===================
+
+> SimpleCloudNotifier is an app to display messages that you can send to your phone with simple POST requests.
+> 
+> After you start the app it generates a UserID and a UserSecret.
+> Now you can send your message to https://simplecloudnotifier.blackforestbytes.com/send.php and a notification will be pushed to your phone.
+> (see https://simplecloudnotifier.blackforestbytes.com/ for an example with curl)
+> 
+> 
+> Use it to
+>  - send yourself automated messages from cron jobs
+>  - notify yourself when long-running scripts finish
+>  - send server error messages directly to your phone
+>  - integrate with other online services
+> 
+> The possibilities are endless*
+> 
+> \* Disclaimer: Developer does not actually guarantee endless possibilities
