+The pager helper will let you display outputs through a pager so the user can easily read and scroll at his will. The helper
+provides two pagers: `less` and  `more`. You will have to fedd them using a closure wrapping code producing output:
+
+```php
+<?php
+
+$app = new Application();
+
+$app
+    ->register('helper:pager:less')
+        ->setCode(function(InputInterface $input, OutputInterface $output) use($app) {
+            $pager = $app->getHelperSet()->get('pager');
+
+            $pager->less(
+                $output,
+                function() {

+                }
