 TNPG is a proprietary service intended to simplify deployment of on-premise installations.
 Deploying a Tinode server without TNPG requires [configuring Google FCM](../fcm/) with your own credentials, recompiling Android and iOS clients, releasing them to PlayStore and AppStore under your own accounts. It's usually time consuming and relatively complex.
 
-TNPG solves this problem by allowing you to send push notifications on behalf of Tinode: you hand a notification over to Tinode, Tinode sends it to  client using its own credentials and certificates. Internally it uses [Google FCM](https://firebase.google.com/docs/cloud-messaging/) and as such supports the same platforms as FCM. The main advantage of using TNPG over FCM is simplicity of configuration: mobile clients don't have to be recompiled, all is needed is a configuration update on the server.
