 ## Usage

+### Sending a Notification To All Users
 
+You can easily send a message to all registered users with the command
 
+    OneSignal::sendNotificationToAll("Some Message");
+    OneSignal::sendNotificationToAll("Some Message", $url);
+    OneSignal::sendNotificationToAll("Some Message", $url, $data);
+
+`$url` and `$data` fields are exceptional. If you provide a `$url` parameter, users will be redirecting to that url.
+
+
+### Sending a Notification To A Specific User
+
+After storing a user's tokens in a table, you can simply send a message with
+
+    OneSignal::sendNotificationToUser("Some Message", $userId);
+    OneSignal::sendNotificationToUser("Some Message", $userId, $url);
+    OneSignal::sendNotificationToUser("Some Message", $userId, $url, $data);
+
+`$userId` is the user's unique id where he/she is registered for notifications. Read https://documentation.onesignal.com/docs/website-sdk-api#getUserId for additional details.
+`$url` and `$data` fields are exceptional. If you provide a `$url` parameter, users will be redirecting to that url.
+
+
+### Sending a Notification To Segment
+
+You can simply send a notification to a specific segment with
+
+    OneSignal::sendNotificationToSegment("Some Message", $segment);
+    OneSignal::sendNotificationToSegment("Some Message", $segment, $url);
+    OneSignal::sendNotificationToSegment("Some Message", $segment, $url, $data);
+
+`$url` and `$data` fields are exceptional. If you provide a `$url` parameter, users will be redirecting to that url.
+
+### Sending a Custom Notification
+
+You can send a custom message with 
+
+    OneSignal::sendNotificationCustom($parameters);
+
