+### Using The front end for failures review
+
+Using the front end to review what's happening in the queue
+-----------------------------------------------------------
+After using Resque for a while, you may have quite a few failed jobs.
+Reviewing them by going over pages when showing 20 a page can be a bit hard.
+
+You can change the param in the url (in the failed view only for now), just add per_page=100 and you will see 100 per page.
+for example: http://www.your_domain.com/resque/failed?start=20&per_page=200.
