+Configuration
+=============
+
+This plugin provides a wizard configuration that will you ask

+Manual configuration
+--------------------
+
+You can manual configure the plugin by adding the plugin properties

+
+```
+[plugin "cloud-notifications"]
+ serverUrl = https://fcm.googleapis.com/fcm/send
+ serverToken = <SERVER_API_KEY>

+```
+
+Plugin parameters
+--------------------
+
+* serverUrl: The Firebase Cloud Messaging backend url.
+Default: https://fcm.googleapis.com/fcm/send
+
+* serverToken: Your Firebase Cloud Messaging server token. You can
+grab it from your Firebase project console, in Configuration > Cloud
+Messaging > Server key
+
+* databasePath: The path to where to store the plugin database. Leave
+empty to use the default path ($gerrit/data/cloud-notifications/cloud-notifications.h2.db)

+Firebase Cloud Notifications Plugin
+===================================
+
+App implementations should register the device token identifier received from FCM, using the *Register Cloud Notification* method to send the device token identifier and configure how it wants to be notified. When registering the device, it also should provide a token, which is returned on every notification, that allows to identify
+the Gerrit instance how send the notification. In addition, an app can configure which events wants to listen to and how the message from FCM is received (as notification, as custom data or received both). Read the FCM documentation to know which is more appropriated for your device operation system. See *Custom Data* in the FCM Notification section to see the information returned as custom data.
+
+A client application can unregistered a device (and stop receiving notifications) from the Gerrit instance using the *Unregister Cloud Notification* method.
+
+Client applications must use a combintion of fcm device identifier + a unique local account token, so they can register to listen notification for different accounts on this Gerrit instance. Token must
+
+
+REST API
+--------
+
+This plugin addes new methods to the /accounts Gerrit REST Api entry point to allow a device to register/unregister to receive event notification in this gerrit instance.
+
+***
+
+**Get Cloud Notifications**
+
+`'GET /accounts/{account-id}/devices/{device-id}/tokens'`
+
+Retrieves a list of registered tokens by a device hold by the Gerrit server instance.
+
+*Request*
+This request requires an authenticated call and only returns information if account-id is the authenticated account. This method returns a list of *CloudNotificationInfo* entities (see below).
