+# Incoming SMS to URL forwarder
 
-## Limitations
-The current version will try to send a text to the URL immediately. If no Internet connection, the app will retry once later.
-The app will not check the HTTP response code. If the server responded with any code, it will be treated as sent.
+## How to use
+Set sender phone number or name and URL. It should match the number or name you see in the SMS messenger app. 
+If you want to send any SMS to URL, use * (asterisk symbol) as a name.  
+
+Every incoming SMS will be sent immediately to the provided URL. 
+If the response code is not 2XX or the request ended with a connection error, the app will try to send again up to 10 times.
+Minimum first retry will be after 10 seconds, later wait time will increase exponentially.
+If the phone is not connected to the internet, the app will wait for the connection before the next attempt.
