 Integrate the GOV.UK API into your service
 ============================================
 
+A client (on github) will make calls to GOV.UK Notify on your behalf. 
+
+You can either:
+* use the user client library provided by Notify - there is currently 1 python library but more will be added in different languages.
+* develop your own ???
+
+To make an IPA call to a client you need:
+* the service ID - this is aviailable on the API keys page on the GOV.UK Notify interface
+* an API key - this is a secret key so save it somewhere safe; do not commit keys to public source code repositories
