+- Make sure that the file whose event is being fired should not end with provided characters.

+    use RTC\Watcher\Watcher;
+
+    require 'vendor/autoload.php';
+
+    Watcher::create()
+        ->addPath(__DIR__ . '/app')

+- Only listen to event with file name that matches given extension(s).

+    use RTC\Watcher\Watcher;
+
+    require 'vendor/autoload.php';
+
+    Watcher::create()
+        ->addPath(__DIR__ . '/app')
