 # Tzeva Adom API
-Async Java API that listens to `Pikud Ha'oref API` and notifies registered listeners as soon as a Tzeva Adom happens.
+Async Java API that listens to `Pikud Ha'oref` and notifies registered listeners as soon as a Tzeva Adom happens.
 
 
 ## How to use
 Let's create a notifier that logs a message when it's Tzeva Adom:
 ```java
 TzevaAdomNotifier
-        .requestFromPikudHaoref()
+        .basedOnPikudHaoref()
         .every(Duration.ofSeconds(3)) //amount of delay between requests
         .onFailedRequest(exception -> LOGGER.error("Failed to request the last alert from Pikud Ha'oref", exception))
         .onTzevaAdom(alert -> LOGGER.info("Tzeva Adom at: " + alert.getCity()))
         .listen(); //async
 ```
 
-You can save the notifier object by calling `build()` instead of `listen()`, in order to add functionality or get data from it:
